Virgin Killer (1976). Virgin Killer is the first of four studio releases that really defined the Scorpions and their highly influential urgent metallic sound. It was released in 1976 and was the first album of the band to attract attention outside Europe. The album was a step in the band's shift from psychedelic music to hard rock. For the first time in the band's career the line-up stayed the same with Klaus Meine on vocals, Uli Jon Roth on lead guitar, Rudolf Schenker on rhythm guitar, Francis Buchholz on bass, and Rudy Lenners on drums. The nine tracks were laid down with Dieter Dierks producing. The band is in top form and churns out some melodic yet blistering heavy rock. Virgin Killer is full of heavy songs and exceptionally, fast, innovative guitar leads by Uli Jon Roth. These songs are infectious and Uli's guitar solo on the Jimi Hendrix inspired "Polar Nights" exhibits the thunder-heavy riffs and grooves that make it a classic…

As a 16-song, single-disc best-of, this does the job very nicely for those who want Nyro's best and most famous songs in one place. Only nine tracks into the CD you've already heard "Sweet Blindness," "Wedding Bell Blues," "And When I Die," "Blowin' Away," "Eli's Comin'," "Stoney End," and "Stoned Soul Picnic," which should be enough to convince anyone that Nyro was a major singer/songwriter. An argument could be made that, as an album-oriented performer whose career spanned about three decades, this is too brief a sampling of her discography, and too lopsided, as just one of the songs was recorded after 1970 (at which point she had yet to reach her 25th birthday). Still, the hard facts are that Nyro's best recordings and compositions were those from the beginning of her career.

The raw immediacy and tight instrumental attack of the Paul Butterfield Blues Band's self-titled debut album were startling and impressive in 1965, but the following year, the group significantly upped the ante with its second LP, East-West. The debut showed that Butterfield and his bandmates could cut tough, authentic blues (not a given for an integrated band during the era in which fans were still debating if a white boy could play the blues) with the energy of rock & roll, but East-West was a far more ambitious set, with the band showing an effective command of jazz, Indian raga, and garagey proto-psychedelia as well as razor-sharp electric blues. Butterfield was the frontman, and his harp work was fierce and potent, but the core of the band was the dueling guitar work of Mike Bloomfield and Elvin Bishop, especially Bloomfield's ferocious, acrobatic solos, while Mark Naftalin's keyboards added welcome washes of melodic color…

A Space in Time (1971). A Space in Time was Ten Years After's best-selling album. This was due primarily to the strength of "I'd Love to Change the World," the band's only hit single, and one of the most ubiquitous AM and FM radio cuts of the summer of 1971. TYA's first album for Columbia, A Space in Time has more of a pop-oriented feel than any of their previous releases had. The individual cuts are shorter, and Alvin Lee displays a broader instrumental palette than before. In fact, six of the disc's ten songs are built around acoustic guitar riffs. However, there are still a couple of barn-burning jams. The leadoff track, "One of These Days," is a particularly scorching workout, featuring extended harmonica and guitar solos. After the opener, however, the album settles back into a more relaxed mood than one would have expected from Ten Years After…

Following the extremely warm reception given his self-named band's well-deserving debut album, Holy Diver, Ronnie James Dio figured there was no point in messing with a winning formula, and decided to play it safe with 1984's sophomore effort, The Last in Line - with distinctly mixed results. Although technically cut from the same cloth as those first album nuggets, fist-pumping new songs like "We Rock," and "I Speed at Night" curiously went from good to tiresome after just a few spins (a sign that the songwriting clichés were starting to pile up…read on); and the otherwise awesome, seven-minute epic, "Egypt (The Chains Are On)," inexplicably lost it's strikingly sinister main riff halfway through, in what sounds like a mastering snafu of some kind. On the upside, more dramatic, mid-paced numbers such as the title track, "One Night in the City," and "Eat Your Heart Out" - as well as the driving "Evil Eyes" - delivered enough compelling riffs and melodies…

Arriving in 1967, Greatest Hits does an excellent job of summarizing Dylan's best-known songs from his first seven albums. At just ten songs, it's a little brief, and the song selection may be a little predictable, but that's actually not a bad thing, since this provides a nice sampler for the curious and casual listener, as it boasts standards from "Blowin' in the Wind" to "Like a Rolling Stone." And, for collectors, the brilliant non-LP single "Positively Fourth Street" was added, which provided reason enough for anybody that already owned the original records to pick this up. This has since been supplanted by more exhaustive collections, but as a sampler of Dylan at his absolute peak, this is first-rate.

Sometimes, a greatest-hits set is timed perfectly to gather together a group's most successful and familiar performances just at the point when that group has passed the point of their maximum exposure to the public, but before the public memory has had a chance to fade. That was the case when Columbia Records assembled this compilation for release in early 1972. At that point, Blood, Sweat & Tears had released four albums and scored six Top 40 hits, each of which is heard here. But lead singer David Clayton-Thomas had just quit the group, so that the unit that recorded songs like "You've Made Me So Very Happy" was not working together anymore. And even when Clayton-Thomas returned, the band would continue to decline commercially. As such, BS&T's Greatest Hits captures the band's peak in 11 selections–seven singles chart entries, plus two album tracks from the celebrated debut album when Al Kooper helmed the group, and two more from the Grammy-winning multi-platinum second album.

On this, the second Spirit album, the group put all of the elements together that made them the legendary (and underrated) band that they were. Jazz, rock & roll, and even classical elements combined to create one of the cleanest, most tasteful syntheses of its day. The group had also improved measurably from their fine debut album, especially in the area of vocals. The album's hit single, "I Got a Line on You," boasts especially strong harmonies as well as one of the greatest rock riffs of the period. The first side of this record is a wonderful and seamless suite, and taken in its entirety, one of the greatest sides on Los Angeles rock. The CD reissue also boasts some excellent bonus tracks. "So Little to Say" is one of Jay Ferguson's finest compositions ever, and the jazz-inspired instrumentals such as "Fog" and "Space Chile" showcase pianist John Locke as one of the most inspired and lyrical players in the rock idiom to date. All in all, a classic album and a true landmark.

Joni Mitchell reached her commercial high point with Court and Spark, a remarkably deft fusion of folk, pop, and jazz which stands as her best-selling work to date. While as unified and insightful as Blue, the album – a concept record exploring the roles of honesty and trust in relationships, romantic and otherwise – moves away from confessional songwriting into evocative character studies: the hit "Free Man in Paris," written about David Geffen, is a not-so-subtle dig at the machinations of the music industry, while "Raised on Robbery" offers an acutely funny look at the predatory environment of the singles bar scene. Much of Court and Spark is devoted to wary love songs: both the title cut and "Help Me," the record's most successful single, carefully measure the risks of romance, while "People's Parties" and "The Same Situation" are fraught with worry and self-doubt (standing in direct opposition to the music, which is smart, smooth, and assured from the first note to the last).

The follow-up to the breakthrough Headhunters album was virtually as good as its wildly successful predecessor: an earthy, funky, yet often harmonically and rhythmically sophisticated tour de force. There is only one change in the Headhunters lineup – swapping drummer Harvey Mason for Mike Clark – and the switch results in grooves that are even more complex. Hancock continues to reach into the rapidly changing high-tech world for new sounds, most notably the metallic sheen of the then-new ARP string synthesizer which was already becoming a staple item on pop and jazz-rock records. Again, there are only four long tracks, three of which ("Palm Grease," "Actual Proof," "Spank-A-Lee") concentrate on the funk, with plenty of Hancock's wah-wah clavinet, synthesizer textures and effects, and electric piano ruminations that still venture beyond the outer limits of post-bop.
