I've always liked 91.3 as a side show, nice alternative to the classic Pittsburgh radio stations. But upon returning to the Burgh a few years ago after a 15 year hiatus minus holidays for a few days, they've really stepped up their game.
They used to be too singer song writingly which is cool a couple of times a week at the local coffee house, but 24-7 it becomes a bit much. That was the old 91.3, the new 91.3 is one of the best radio stations I've been exposed too. Even in the age of Pandora, Spotify, and online radio, I've still discovered new music here and live music events as well. Rock On!
