A few months ago, we performed at a private party for a lovely group of people who asked us to play several sets of purely improvised instrumental music, accompanied by friends new and old on light projections and auxiliary sounds. This record is a collection of the best moments from that special night.

Jefferson Airplane's first live album demonstrated the group's development as concert performers, taking a number of songs that had been performed in concise, pop-oriented versions on their early albums – "3/5's of a Mile in 10 Seconds," "Somebody to Love," "It's No Secret," "Plastic Fantastic Lover" – and rendering them in arrangements that were longer, harder rocking, and more densely textured, especially in terms of the guitar and basslines constructed by Jorma Kaukonen and Jack Casady…

Rock & roll had grown louder and wilder by leaps and bounds during the '60s, but when Blue Cheer emerged from San Francisco onto the national rock scene in 1968 with their debut album, Vincebus Eruptum, they crossed a line which most musicians and fans hadn't even thought to draw yet. Vincebus Eruptum sounds monolithically loud and primal today, but it must have seemed like some sort of frontal assault upon first release; Blue Cheer are often cited as the first genuine heavy metal band, but that in itself doesn't quite sum up the true impact of this music, which even at a low volume sounds crushingly forceful…

Even among Deadheads, there's always been a sense that Jerry Garcia's studio albums have been somewhat ignored. Part of this ties back to the often repeated urban legend that the Grateful Dead were never as good in the studio as they were live – an argument that has some truth but tends to downplay the merits of the studio albums, which had their own distinct attributes. This also applies to Garcia's studio records, but as a whole they're more problematic than the Dead's catalog…

Controversial at the time, delayed because of fights with the record company over lyrical content and the original title (Volunteers of America), Volunteers was a powerful release that neatly closed out and wrapped up the '60s. Here, the Jefferson Airplane presents itself in full revolutionary rhetoric, issuing a call to "tear down the walls" and "get it on together." "We Can Be Together" and "Volunteers" bookend the album, offering musical variations on the same chord progression and lyrical variations on the same theme…

Gong slowly came together in the late '60s when Australian guitarist Daevid Allen (ex-Soft Machine) began making music with his wife, singer Gilli Smyth, along with a shifting lineup of supporting musicians. Albums from this period include Magick Brother, Mystic Sister (1969) and the impromptu jam session Bananamoon (1971) featuring Robert Wyatt from the Soft Machine, Gary Wright from Spooky Tooth, and Maggie Bell…

The Doors returned to crunching, straightforward hard rock on Morrison Hotel, an album that, despite yielding no major hit singles, returned them to critical favor with hip listeners. An increasingly bluesy flavor began to color the songwriting and arrangements, especially on the party'n'booze anthem "Roadhouse Blues."…

Fare Thee Well: Celebrating 50 Years of the Grateful Dead is a live album consisting of audio and video recordings from the Fare Thee Well: Celebrating 50 Years of the Grateful Dead concerts performed by surviving members of the Grateful Dead Bob Weir, Phil Lesh, Bill Kreutzmann, and Mickey Hart, with Trey Anastasio, Bruce Hornsby and Jeff Chimenti…

THINK FLOYD pulls of a decent tribute to PINK FLOYD, and it's a nice listen for those who won't be bothered by band's unoriginality (they are a tribute band, get over it)…

A welcome return to their lightest and wispiest styles, with clear, shimmering instrumental textures that are almost like sonic waterfalls. Their enigmatic, moody song structures and melodies remain, with the most histrionic edges of Annisette's vocals toned down…

With contributions by noted jazz saxophonist Ben Webster and the American gospel quintet the Stars of Faith, this is (along with Refugee) their most R&B-influenced recording, at times achieving a churchy, old-time New Orleans-like feel…

Your Daily Gift opens with an original pop/rocker, "Sunday Morning," which displays Anisette's little granny voice to great effect. This is not the hit song by Spanky & Our Gang, nor does Anisette sound anything like Spanky, but the two bands would have complemented each other nicely on a bill, and had Elaine McFarlane performed "The Waters Run Deep," the first song on side two, it might have been an American hit…

The Doors, one of the most influential and controversial rock bands of the 1960s, were formed in Los Angeles in 1965 by UCLA film students Ray Manzarek, keyboards, and Jim Morrison, vocals; with drummer John Densmore and guitarist Robby Krieger. The group never added a bass player, and their sound was dominated by Manzarek's electric organ work and Morrison's deep, sonorous voice, with which he sang and intoned his highly poetic lyrics…

Best-known for his 1970 hit "Spirit in the Sky," singer/songwriter Norman Greenbaum was born November 20, 1942, in Malden, MA. He began his musical career while a student at Boston University, playing area coffeehouses before relocating to the West Coast during the mid-'60s and forming a kind of psychedelic jug band dubbed Dr. West's Medicine Show and Junk Band…
