The ultimate in indie collections, this 2 CD set is part of the Red Hot series, which has been collecting money for AIDS charities for 20 years now. Curated by Aaron and Bryce Dessner of The National, there are 31 new and exclusive tracks here, and I think is worth buying for the Gillian Welch and Conor Oberst duet alone. But you also get Bon Iver, Feist, Iron & Wine, Decemberists, Arcade Fire, My Morning Jacket, Jose Gonzalez, Cat Power, Sufjan Stevens etc. Recommended.
