Vanilla Fudge is an American rock band known predominantly for their slow extended heavy rock arrangements of contemporary hit songs, most notably "You Keep Me Hangin' On".
The band's original line–up — vocalist and organist Mark Stein, bassist and vocalist Tim Bogert, lead guitarist/vocalist Vince Martell, and drummer and vocalist Carmine Appice — recorded five albums during the years 1967–69, before disbanding in 1970. The band is currently touring with three of the four original members: Stein, Martell, and Appice with Pete Bremy on bass as Bogert retired in 2009.

Tommy is the fourth studio album by the English rock band The Who, a double album first released in 23 May 1969. The album was mostly composed by guitarist Pete Townshend, and is a rock opera that tells the story of Tommy Walker, a "deaf, dumb and blind" boy, including his experiences with life and his relationship with his family.

Electric Warrior is a 1971 album by Marc Bolan's band T. Rex, their sixth since their debut as Tyrannosaurus Rex in 1968, and their second under the name T. Rex. The album marked a turning point in the band's sound, moving away from the folk-oriented music of the group's previous albums and pioneering a flamboyant, pop-friendly take on electric rock & roll known as glam rock.
The album reached number 1 on the UK charts and became the best selling album of 1971. The single "Get it On" reached the top ten in the US Billboard Hot 100 singles chart. Retitled "Bang A Gong (Get It On)" by the US record company, it also became the band's only hit in North America.
Electric Warrior has since received acclaim as a pivotal release of the glam rock movement.

This is my favorite Kazu Matsui recording. I have others but this one with Robben Ford is very good. If you are a fan of Robben Ford, you get to hear a different side of him. Great vocalsl from Robben. I have been looking for this album in CD format for years. A must have for Kazu Matsui Project fans and Robben Ford fans.

"In-A-Gadda-Da-Vida" (derived from "In the Garden of Eden") is a song recorded by Iron Butterfly and written by bandmember Doug Ingle, released on their 1968 album In-A-Gadda-Da-Vida.
At slightly over 17 minutes, it occupies the entire second side of the In-A-Gadda-Da-Vida album. The lyrics are simple, and heard only at the beginning and the end. The track was recorded at Ultrasonic Studios in Hempstead, Long Island, New York.
In 2009, it was named the 24th-greatest hard rock song of all time by VH1. It is also often regarded as an influence on heavy metal music and one of the firsts of the genre.

From the Mars Hotel is the seventh studio album by rock band the Grateful Dead. It was mainly recorded in April 1974, and originally released June 27, 1974. It was the second album by the band on their own Grateful Dead Records label. From the Mars Hotel came less than one year after their previous album, Wake of the Flood, and was the last before the band's then-indefinite hiatus from live touring, begun in October 1974.

Blues for Allah is the eighth studio album by the Grateful Dead. It was recorded February 27 – May 7, 1975, and released September 1, 1975. It was the band's third album on their own Grateful Dead Records label and their third studio album in a row. Though it has not received RIAA certification as of 2020, Blues for Allah was the group's highest-charting album until 1987's In the Dark, reaching No. 12 during a thirteen-week stay on the Billboard Album Chart.

Critical reaction to the album has been largely positive. At the time of release Robert Christgau said the album contained "AM and FM faves" which were "served hot, raw, or both". "Ultimate Classic Rock" ranked the album in the "Top 100 Live Albums", and suggested that it was superior to the studio albums recorded by Clapton at the time.

Backless is the sixth full-length studio album by Eric Clapton. Produced by Glyn Johns, and released by RSO Records, Backless reached No. 8 on the pop charts. While the single "Promises" only reached No. 37 in the UK, it was a much bigger success in the US, reaching No. 9 on the Billboard charts. The follow-up single, "Watch Out for Lucy", was the B-side of "Promises", but reached #40 on the Billboard charts on its own merit. This was Clapton's last studio album to feature his longtime bassist Carl Radle who died in 1980.

Baby I'm-a Want You is the fourth album by Bread, released in 1972. Its singles included the title cut (which reached No. 3 on the Billboard Top 100), "Everything I Own" (No. 5), "Mother Freedom" (No. 37), and "Diary" (No. 15). This was the first Bread album to feature keyboards player Larry Knechtel.

Permanent Waves is the seventh studio album by Canadian rock band Rush, released on January 14, 1980, through Anthem Records. After touring to support their previous album, Hemispheres (1978), the band began working on new material for a follow-up album in July 1979. This material showed a shift in the group's sound towards more concise arrangements and radio friendly songs (such as "The Spirit of Radio" and "Freewill"), though their progressive rock blueprint is still evident on "Jacob's Ladder" and the more than nine-minute closer "Natural Science". Bassist/vocalist Geddy Lee also employed a more restrained vocal delivery compared to previous albums. Permanent Waves was recorded in 1979 at Le Studio in Morin-Heights, Quebec with production handled by the group and Terry Brown.

Signals is the ninth studio album by Canadian rock band Rush, released on September 9, 1982 by Anthem Records. After the release of their previous album, Moving Pictures, the band started to prepare material for a follow-up during soundchecks on their 1981 concert tour and during the mixing of their subsequent live album Exit...Stage Left. Signals demonstrates the group's continuing use of synthesizers, sequencers, and other electronic instrumentation. It is the last album produced by their longtime associate Terry Brown, who had worked with them since 1974.
