Heeb's psychedelic Diamond Days Music Festival is happening in Brooklyn this weekend. Tonight and Saturday you can get your fill of prog rock at the Church of the Messiah in Greenpoint, and then on Sunday Heeb's hosting an all-day BBQ at Union Pool.

The shows are $10 a day or $25 for a weekend pass. BYOB on Friday and Sunday, all ages. There will be mystic storytelling as well, so brush up on your Kabbalah.
