Never saw Mike Pinera that I recall.
I saw Iron Butterfly in 1969 and missed Mike Pinera by a year but that’s OK. The original Iron Butterfly guitarist captured that In-a-gadda-da-vida vibe well.
May Mike RIP.
Just read this the other day:
Ron Bushy’s drum solo was the inspiration for Ringo Starr’s drum solo on “The End” from the Beatles’ 1969 album Abbey Road. It was the last song recorded collectively by all four Beatles
