Hendrix in '67 in Santa Barbara, Zep in '69 (my little band opened for them and technically it was the second part of their first tour) in Honolulu, Tull in '69...note that Tull and Zep made pretty much every other band (except Hendrix of course) seem like they were "loitering"...not my term but somebody in Rolling Stone back then said that...perfectly.
