Local indie rockers Bound Stems unveiled their sophomore LP, The Family Afloat (Flameshovel), on vinyl and MP3 back in July. This Tuesday they'll be at Bucktown bar and grill Silver Cloud (1700 N. Damen) from 8 to 10 PM to celebrate the album's incarnation in CD form. The Stems will play a free acoustic set, and there'll be $2 cans of beer.
