*May Blitz was a Canadian-British psychedelic rock power trio that was active in the early 1970s.
The group was formed in the UK during 1969 by bassist Terry Poole and drummer Keith Baker, the rhythm section of the blues-rock trio Bakerloo, both of whom left the group when guitarist Clem Clempson departed to join Colosseum. Jamie Black joined the group on vocals and guitars but both Poole and Baker left the group before it recorded, Poole joining Vinegar Joe and Baker Uriah Heep. Black then added fellow Canadian Reid Hudson (Victoria B.C.) on bass and Tony Newman, who had played with Jeff Beck, The Hollies and Sounds Incorporated, on drums.* Partial biography from Wikipedia
