Daytrotter is a website for the recording studio Horseshack, which hosts recording sessions with many popular and upcoming indie music (typically) acts, although it works with local bands in the Illinois area as well. The sessions can be compared to that of a radio station's lounge recordings, where musicians passing through the town can do a semi-live song. Due to their tendency to offer an eclectic sampling of music, and their production style (see Studio section below) the sessions have been compared to that of the legendary Peel Sessions.
