In 1972, Frank Zappa experimented with an "electric orchestra" concept which resulted in 2 albums: Waka/Jawaka and The Grand Wazoo. Celebrating the 50th-anniversary of this endeavor, Waka/Wazoo documents the recording sessions with outtakes and oddities on 4 CDs. Also included is a December 1972 live show from Winterland Ballroom in San Francisco and unreleased George Duke demos.

Red Sea is the second album by English hard rock band Warhorse. The CD reissue has six previously unreleased bonus tracks, including a live version of "Ritual" (a song from the first Warhorse album) and five demos of Nick Simper compositions that do not appear on the two Warhorse LPs. Warhorse were a band formed by former Deep Purple bassist Nick Simper. He had left Deep Purple in 1969 and joined Marsha Hunt's backup band. Not long after, Nick Simper replaced her backing band with Ged Peck on guitar and Mac Poole on drums. While this was going on, Simper would play in an extracurricular band along with Ged and Mac, with singer Ashley Holt.

After two late-'60s albums on Columbia, Johnny Winter hit his stride in 1970 working with Rick Derringer and the McCoys, now recruited as his sidemen and collaborators (and proving with just about every note here how far they'd gotten past "Hang on Sloopy"). In place of the bluesy focus on his first two albums, Winter extended himself into more of a rock-oriented mode here, in both his singing and his selection of material. This was hard rock with a blues edge, and had a certain commercial smoothness lacking in his earlier work. Derringer's presence on guitar and as a songwriter saw to it that Winter's blues virtuosity was balanced by perfectly placed guitar hooks, and the two guitarists complemented each other perfectly throughout as well.

Neo was the name of a French quintet that performed instrumental Progressive rock, and was led by bassist André Paul and saxophone player Didier Erard (French Kiss). This line-up issued their unique eponymous album in 1980. Their compositions are based on melodies with occasional breaks, rhythms changes, accelerations, colours as well as changing and sophisticated atmospheres. The themes are very elaborated, complex and not quite straight and easy. The instrumental dialogues are numerous: a rageous or cutting edge guitar answers to inventive keyboards or to a whirling saxophone line. The band can successively remind of Bo Hansson, Camel (Mel Collins's period) or Caravan, and sometimes King Crimson ("Islands" days).
