Watch Coldplay Perform at ACL Music Festival
British rock band Coldplay entertained tens of thousands of people with their songs during their concert at the 2011 ACL Music Festival held at Austin, Texas' Zilker Park on Friday night (September 16th) - As it's usual, band leader Chris Martin gave his all, singing every lyric of every song with SUCH passion, and demonstraiting he's a great vocalist at the same time. The Austin crowd responded really well, cheering and singing along, and check out the pretty cool moment during the 'Viva La Vida' performance, where they immediately began shouting the 'oh, oh, oh, oh' bits when they recognized Chris' piano notes. So summing up, watch below HQ performances of, "Paradise" (FIRST live presentation), "Charlie Brown", and "Viva La Vida". A day before the ACL Festival, Coldplay participated at the taping of the television show "Austin City Limits". There, the English rockers DEBUTED their new track "Up In Flames". See below too.
