I just finished listening to Alaska play the mainstage. They won the 'Best of White Elephant" at Parachute Festival 2011 and my kids heard them many times. I told you they were worth checking out!!!! They have a harpist and violinist in the band and have a unique sound – a bit like Radiohead, actually, and they even did a Radiohead cover.
You can download Alaska's music here.
Other great bands here: Skillet rocked! – I had never heard them before but their sound is amazing. And Brian Welch made a good impression on the Parachute crowd through his music, his talks and through encouraging guitar skills in the workshops.
