I was briefly involved with WITR during my undergrad. Loved what they were doing, but at that time the station definitely bought into the hipster attitude, music you've never heard of and will never hear again.

The only band I can remember hearing on WITR, then hearing anywhere else, is Neon Indian. They also sponsored a concert with Viva Brother, which briefly got some airplay on other stations, in spite of never (to my knowledge) having played them.
