i was 16 when a mate asked if i join him to see this young American band called Nirvana. said no, needed the money for beers on the weekend innit. oh well.

Zeppelin (saw the Reunion in 2007 but too young for the hey days)

Nirvana (had an opportunity but preferred beers on the weekends, i was young so priorities differed)

13th Floor Elevators

Beethoven

Leadbelly

Johnny Cash

but luckily ticked off my wish list pretty well. from those alive it's really only Tom Waits i would love to see, but the dude isn't about much. Oh and Rodriguez.

Love Keith Jarrett and can't imagine that anyone exists who doesn't like The Koln Concert.
