Sadly looks like the above link has 'died' in the recent NMA board spring clean. Whatever it is and whatever the mix contains it certainly gets you in the mood pre gig, but also there this tremendous feeling of anticipation 15 mins before NMA take to the stage anyway which always helps - cos adrenalin is the strongest drug that there has ever been...
My bad for the link, the forum add an additional "http" at the beginning, edited

To me, it's not whatever music before the gig, it's really not that often that a band take the time to play music they like before a show, and by this way try to makes you discover music they like. Covers are a great way for that too (I get into The Ruts much more after hearing a cover of "In a Rut" by NMA in 1991 during a gig in Caen, even if Justin didn't helped to find out which band it was by just saying something like "this should be part of everybody musical education" and by mixing the song, if I'm correct, with a The Animals song, "We've Gotta Get Out of This Place"

). And I had to listen again to Queen of the Stone Age after that Justin told me it was his favorite band of the moment (was around 2002 if I'm correct), even if I still not really enjoyed the band after that

(that was just to mention what I discovered by NMA, many bands made me dig for music after I discovered that one of their song was a cover too).
Music is something to share (and don't take this as a "go download everything", I mean like the tapes we used to do for friends in school, to make them discover what we recently bought, I still remember my first NMA tape, made by a friend).
