Really too many to list.
Spent almost every week seeing bands from age 19 to 24\. Saw festivals and gigs travelling
Highlights
Springsteen in Philly. One of the last shows with the full E Street band. (Danny died after the first leg of the tour)
U2\. Have seen them everytime they have come out since ZooTV but ZooTV still rates as a massive highlight
Chemical Brothers. Manchester 2001.
Michael Franti & Spearhead. Every tour since Chocolate Supahighway
Coldplay Earls Court in 03
Radiohead on every tour
Massive Attack Opera House forecourt 2010.
The Cure Opera House at Vivid last week (AMAZING)
Rage Against The Machine in San Fran 1999 just before the Woodstack fiasco
REM Monster tour
Tori Amos at the Opera House 2009
Pearl Jam a few times
Metallica a few times before Load came out
Rock In Rio 3 in 2001 featured Beck, Dave Matthews Band, Foo Fighters, Guns N' Roses, James Taylor, Neil Young, Oasis, Queens of the Stone Age, Red Hot Chili Peppers, R.E.M., Sting and maybe Maiden & Silverchair were there as well. Not a 100% memory of that night Great trip away, brilliant festival
