Poseidon
There are several bands named Poseidon:
1. A german prog/krautrock band formed in 1974 who released a single album in '75 called "Found My Way". The album got re-released by german label "Garden of Delights" with seven bonus tracks in 2001. The band was:

The Other Half
This obscure San Francisco '60s band gained a degree of notoriety in the '80s when their punk-garage single "Mr. Pharmacist" was included on one of Rhino's Nuggets compilations and covered by the Fall. Actually, most of the Other Half's material was far less garage than psychedelic, featuring the sustain-laden guitar of Randy Holden, one of the best Jeff Beck-inspired axemen of the '60s. Boasting a just-out-of-the-garage approach to Haight-Ashbury psychedelia, the group cut a little-heard, fairly strong album, as well as a few rare singles, in 1967 and 1968.
Jumbo
Jumbo is a name that has been used more than once.(1) is a musical group from Monterrey, Mexico. (2) was an Italian progressive rock band of the 70s. (3) Late 90's indie group from Newcastle, UK.

Iron Claw
Iron Claw is a rock band which formed in Dumfries, Scotland in 1969. The band was formed by original members Jimmy Ronnie, Ian McDougall, and Alex Wilson. They were joined by singer Mike Waller in 1970. Wilson, the group's bass guitarist, decided to form a band after seeing a Led Zeppelin concert in 1969 and the band was eventually named after a lyric from King Crimson's "21st Century Schizoid Man". The band originally performed covers by blues rock artists such as Free, Johnny Winter, Ten Years After, and Taste but soon began writing and performing original compositions.
Necronomicon
1) Necronomicon were formed in 1971 in Aachen, the Western part of Germany near the Belgium and Netherlands border. With an album title (Tips zum Selbtsmord) that means "How to Commit Suicide," Necronomicon's one album, from 1972, featured bleak progressive garage rock with long instrumental passages. With wailing acid guitar solos, dark organ swirls, and angst-ridden singing in German, Necronomicon has created a dark and powerful vision that blends psychedelic and progressive music with a proto-punk garage band sensibility.
Ginhouse
Hard rock trio from Newcastle whose album is now rare. They had a good reputation as a live act and wrote some strong material on their album, with the continuous track "The House"/"Sun In A Bottle" the highlight, alongside a cover version of The Beatles' "And I Love Her". Geoff Sharkey had earlier played in Sammy.
