OK, so I'm a huge fan of the A.V. Club's AV Undercover series.
For the uninitiated, 25 songs are chosen by the A.V. Club and its readers. Each week, a band comes in and covers one of the songs. After a band plays the song, it comes off the list. They range from the really good to the eh...
So far, a new possibility has been introduced: covering songs from the NG Audio Portal.
