I need some help finding songs to listen to from these bands.

I am going to the All Points West Concert to see Jack Johnson. But I also want to get to know some of the other acts in the show because I am not as familiar with them. Some of the band I am interested in getting to know is Ben Harper & The Innocent Criminals, Cat Power, Rodrigo y Gabriela, Amadou & Mariam, The Secret Machines, Jason Isbell, Matt Costa, Robyn and De Novo Dahl. So any suggestions you can give me would be very helpful.

Also I registered at http://www.flickr.com/groups/jackatapwfest/ for free tickets to the show, so if I win I may be looking to sell my ticket master tickets at a discount price if anyone would be interested.

Thank you so much for your help! Hope to see you guys at the show!
