Pearl Jam...always Pearl Jam. Love their music...
DS 32 took me to a concert several years ago...it was awesome; we were in the 11th row. Except for the mosh pit next to me, it was one of the best I've been to.
I saw John Mayer last year...if he'd keep his trap shut it would have been better...he's a boor, but one of the best guitarists around. Never understood what J Anniston saw in him...

DS30 took me to the Crossroads Festival a couple of years ago...wow!! Clapton, Bramhall, Derek Trucks and Susan Tedeschi, Johnny Winter, Vince Gill, Sheryl Crow (great), B B King, Buddy Guy (one of my favs), on and on..
he also took me to se Jonny Lang several times. He is one of the most talented guitarists in the world.
If they were still alive I'd love to see Stevie Ray Vaughn and John Lennon...
