These guys are incredible. Spent last evening familiarizing myself with their repertoire and now my iPod is updated with their music. My young staff members laugh at me -- I am so into my iPod nano.
You can also listen at jango.com, another guilty pleasure of mine: free internet radio that you customize to your own musical tastes. My "station" features Tanghetto, Gotan Project, D J Shadow, Fatboy Slim, Thievery Corporation, for instance. And you can send songs to others. Cool.
