This is guitar hero Alvin Lee giving it his all at the Isle of Wight festival, 1970. On the bill were Jimi Hendrix, Free, Chicago, The Who, Joan Baez.
Greatest of all for me was Miles Davis (who showcased 'Bitches Brew') and Joni Mitchell but young people still fall over with envy when I tell them I saw Hendrix live. All the critics say it wasn't Hendrix at his best. All I can say is that it did for me.
I always found I could get good stuff of musicians. Being a photographer around musicians was always magical for me. I play guitar but unfortunately lack any talent.
A talentless musician has a much harder time of it than a talentless photographer - I'm glad to say.
