Tear Gas (1971)

alexgitlin.com:

"These Glasgow-based progressive/heavy rockers were originally known as Mustard. Their first vocalist Andy Mulvey had previously been with The Poets. However, he was soon replaced by David Batchelor and around the same time Gilson Lavis (their original drummer, who later played with Squeeze) was replaced by Richard Monro from Ritchie Blackmore's Mandrake Root. This line-up recorded Piggy Go Getter, which made little impact. In 1970, Hugh McKenna took over Batchelor's vocal role and Ted McKenna (ex-Dream Police) relieved Monro on drums. They recorded a second album and tried to establish themselves on the underground scene but were going nowhere with their brand of tired boogie heavy rock, until they teamed up with Alex Harvey in August 1972 to become The Sensational Alex Harvey Band."

FreakEmporium:

"UK (Scottish) early '70s band featuring Zal Cleminson who made this killer album which is a hard edged progressive acid rock masterpiece in the same league as T2's debut. Great guitar work that at times has a Floyd feel and at other times the energy and attack of Hendrix. Multi layered vocal harmonies and some wonderful songs. Contains extra track with vocals by Alex Harvey. Essential." (buy it)
