This incredibly diverse collection was Chicago’s sixth studio album and their final studio-recorded double album to date. Cited for its jazz excursions, Chicago VII reached No. 1 in the US and included three stand-out hits including Searchin’ So Long, Wishing You Were Here and the first single penned by trumpeter Lee Loughnane Call on Me, which reached No. 6 in the US.

String Driven Thing may have disintegrated when Chris and Pauline Adams departed, but Graham Smith didn't let that deter him. He rebuilt the band from the foundation up and shifted the focus from progressive folk to a more straight-ahead rock & roll format, a sonic sensibility helped along by vocalist Kim Beacon, whose Rod Stewart-styled vocals provided a front to the heavy-hooked guitar-driven songs. The new format didn't win many points with the band's old fans, but String Driven Thing's more pop-oriented sound fit perfectly with the mainstream marketplace's own drift away from the prog-tinged seas that the band once sailed so masterfully.

After gaining some recognition from the success of the band's previous album, Bachman-Turner Overdrive got around to recording Not Fragile. Not only had one of the three Bachman brothers (Tim, the rhythm guitarist) left the band to BTO's advantage, but Randy Bachman and C.F. Turner had clearly grown musically. To the album's benefit, most of the material on Not Fragile are the band's much-liked rock anthems, ranging from the hyper-distorted title track, through the famous but far more timid song "You Ain't Seen Nothing Yet." Indeed, for hard rock fanatics, it doesn't come much better than on Not Fragile. Randy's electrifying lead guitar is here more raucous than ever before, as are his rowdy vocals (particularly noticeable on the predictable, but fun "Sledgehammer"). The man steals the show on Not Fragile through his extensive and often astounding guitar solos…

One More River To Cross is the tenth studio album by Canned Heat, released in 1973. The band negotiated out of their contract with Liberty Records and debuted with Atlantic Records. This album featured horn arrangements played by the Muscle Shoal Horns along with Barry Beckett and Roger Hawkins. The album cover was designed by Ernie Cefalu.

There's the Rub is the fifth studio album by rock band Wishbone Ash. It is the first album to feature guitarist/vocalist Laurie Wisefield, who would be a major part of the band's creative direction for the next 11 years. The album is considered by many to be a highpoint of the band's recording career. The title is taken from Shakespeare's Hamlet; "To sleep—perchance to dream: ay, there's the rub." The track "F.U.B.B." caused controversy because of the acronym's meaning ("Fucked Up Beyond Belief") upon the album's release. Moreover, the haunting ballad "Persephone" would go on to become one of the band's most popular live songs. The lyrics of "Lady Jay" are based on the Dartmoor folk legend about Kitty Jay.

Despite her Latin heritage, Joan Baez probably wouldn't have been encouraged by her 1960s record label, the New York-based independent Vanguard, to sing an entire album in Spanish. At A&M Records, the Los Angeles firm co-founded by Herb Alpert that she joined in the early '70s, however, it would have been a different story, and it was A&M that released Gracias a la Vida ("Here's to Life") in 1974. Baez demonstrates an affinity for Mexican folk music on such obvious choices as "Cucurrucucu Paloma," but it's no surprise that, a year after the assassination of leading nueva canción folksinger Victor Jara in a military coup in Chile, an atrocity that shocked the American folk community, she has not backed away from her political commitments…

Murple unfortunately released only one album (until their belated reunion in 2008) titled "Io Sono Murple" which stands out as a superb piece of 70's Italian Progressive Rock. Centred around the symphonic keyboard and piano work of Pier Carlo Zanco this album blends all of the progressive rock characteristics that made this such a beloved region for this art rock genre. Comprised of just two lengthy tracks (side one and side two) "Io Sono Murple" draws on the classic 70's Ital-prog vibes with gorgeous piano and synthesizer work mixed with fantastic guitar, bass and drum interplay. The 2 songs are both drop dead fantastic and contains the romanticism of I Pooh and Locanda delle Fate with the musical prowess PFM.

This Barcelona-based spanish band made their debut in 1972 with their eponymous album. This record is a mostly instrumental one (a few scatting one the opening track), but this does not hamper the enjoyment of the music: they have a fairly unique sound and the music has some very subtle Spanish overtones but not in the Flamenco realm. Their sound oscillates between Isotope, Wigwam (the Gustavson and Pohjola compositions), Focus or Finch, Sloche (or fellow Quebecois Maneige) and countrymen Iceberg. If the jazz colours are the main characteristics of the album, the classical influences peak here and there, most notably in Negra Sombra (Dark Black).
Their second slbum 'Fusioon 2' (1974) comprises a stunning combination of delightful melodies and counterpoints, clever interplaying, delicate dissonances…

In their early years, Kaipa was one of Sweden's best Symphonic Prog bands. Roine Stolt from The Flower Kings was a member of Kaipa. Their albums contain mostly instrumental music, drawing its influences from classic progressive Rock bands (Camel, Yes, Genesis), Classical music (Bach), and also Swedish Folk music. The Decca Years is a compilation of the three first albums from Kaipa, released under the Decca label during the years of 1975 to 1978. It also includes a demo which was previously unreleased, and a previously unreleased live set.
