@ stevie/boxer - lol. I'm old as fuck and have been going to gigs since I was a kid, so over the years I've seen a lot of bands. when you go to see a big band like RHCP/Greenday etc you tend to get decent support acts, so I often got see a lot of good bands I might not have gone to see on their own. For instance when oasis played Knebworth in the UK, their support acts were: The Charlatans, Kula Shaker, Manic Street Preachers, The Bootleg Beatles, The Chemical Brothers, Ocean Colour Scene and The Prodigy.
oh my I forgot the Prodigy! I saw them at Cambridge Corn Exchange just before they released The Fat of the Land! That was a good fucking show, man how did i forget that one.
Same with Linken Park at Milton Keynes, they were supported by: Inner Party System, Enter shikari, The Bravery (urgh). NERD, Pemdulum and Jay Z.
Fesitvals are a great way to see a lot of good bands, my dad took me to Reading when I was 12 and that was my first ever festival. It was an amazing experience plus i got to see a butt ton of bands. RATM were amazing at Glastonbury, I always wished I'd got to see them a smaller gig though. Maybe one day and I'll get the chance :-)
One of my fav gigs was Alice In Chains Rotten Apple and Would? were highlights of the show IMO.
Speacial mention to Minus The Bear - the were amazing live and was so glad I saw them at a small venue.
Oh and add The Clash and The Sex Pistols to the list of bands "I would like to have seen"
