From Passion Pit covering Smashing Pumpkins' "Tonight, Tonight" to the Dirty Projectors covering Dylan's "I Dreamed I Saw St. Augustine," these tracks are amazing. Best of all? They are completely FREE to download. Check it out here: levispioneersessions.com
Of course the John Legend/The Roots track is my favorite. Can't wait for their new collaboration album to be released this fall!
