1. Gloomy pretty Icelandic techno outfit Mum will convince you to drink away your well-considered pain at the Bowery Ballroom.
2. Two-woman satire tears away the veil of secrecy from those troubled Hollywood "stars" and best gal pals Matt and Ben at PS 122.
3. The Fringe Festival presents Meaningless Sex, a multi- and metro-sexual love story... musical.
