Yeah , Pink Fairies and Hawkwind are both considered the next wave of Psych , in the early 70's. Tho' both bands had a Hard Rock bent , too.....So , in that regard , they ARE comparable to Captain Beyond.
Armageddon , with Keith Relf and Bobby Caldwell from Captain Beyond had similar starnge changes in their songs , that are like Captain Beyong , because of Caldwell's drumming. Still , they were even more on the Hard Rock tip....Apparently , they only did one gig , or a string of gigs , in LA.
Cold Sun (Bill Miller , later with Roky Erickson and The ALIENS) , sIMPLY sAUCER , The Ya Ho Wa 13 recordings , and others epitomized early to mid - 70's Psych. Even Blue Oyster Cult's first Lp.
I don't think most people consider The Sabs Psychedelic , but , there's songs like "Planet Caravan" that definitely are.
Hit songs like "Jump Into The Fire" by Nilsson , "Go Back" by Crabby Appleton , "Draggin' The Line" by Tommy James , fit the bill.
I'm no KISS fan , but , "Goin' Blind" , yep. Their version of The Stones' "2000 Man sounds more Glam than Psych to me."
Then there's Johnny Hallyday's early 70's ''Angry Psych ' period. Sounds like a precursor to The Stranglers , with Mick Jones (Yes , later in Foreigner.) on somevery MC5ish leads.
The Groundhogs , too , sound plenty Psychedelic to me.
So many things , at that time , were neither fish nor fowl. Now , it's so cut and dried.
