For those of you not standing on-line right after work so you can get the best seats for the midnight showing of The Dark Knight: Tonight at Jammin’ Java, Jenny Owens Youngs will be playing sweet songs about love and longing. And maybe stripper poles. Seriously, go listen to “Voice on Tape” (featuring Regina Spektor) and “Fuck Was I”, and imagine the possibilities of hearing that haunting beauty and Nelly. Be there at 7:30 p.m., $10 in advance, $12 at the door.
