It’s tough not be impressed by what the folks at Thread Productions are doing. Musically, the five Thread bands–Tartufi, Low Red Land, Birds & Batteries, Silian Rail and newest member Sky Pilots–are among the top in Bay Area indie rock, with a streak of excellent full length albums that, while musically diverse, all capture unique artistic viewpoints.

As the East Bay Express noted, when they named Thread the “Best Band Collective” last year, these bands are committed to supporting each other–resulting in excellent collaborations like last year’s Dragon Slayers, Volume 1, a compilation featuring music by each of Thread’s then-four bands. For Volume 2, which comes out this week, they’ve opened it up to include songs by some of the other Bay Area bands they love, like Or, the Whale and The Aimless Never Miss, plus new and unreleased tracks from the collective members.

On Friday, Thread celebrates the new comp’s release at Bottom of the Hill featuring performances by Tartufi, Silian Rail, Low Red Land and Sky Pilots, who are also celebrating the release of their new CD Enjoy a Day Off at the show. The show starts at 9pm and is $10.
