At 8:30 p.m. tonight at Open Lot (1310 South 18th Street), Brooklyn's ambient noise sculptors Mountains are performing. Ghost Ice and Raglani (together! just to further prove that they're not the same person) and Dave Stone are also on the bill. Tickets are just $6. I wanted to post an MP3 from Mountains' new disc, Choral, but it's twelve minutes long and 30 MB, so no dice although its label, Thrill Jockey, has the LP streaming here.
