Mylene Sheath are not only the best, most dedicated to their bands/releases label going right now, but they're the happiest and sweetest people. Lindsay & Joel care deeply about their bands, releases, and fans. They genuinely love and are rabid fans of the music they put out. And I love them for exactly those reasons.
EDIT - And I happily back Sargent House as well. They take care of Russian Circles and I fucking love Russian Circles.
This was a great read. Where can I see the first list?
Shameless plug: Brookvale Records based out Long Island, owned by Karl Groeger, who also owns Looney Tunes record store, is new but going to do great things for Tiger Riot, Hotel of the Laughing Tree and Grace Read!
Diplo's Record Label Mad Decent! Not at all the same genre but putting out a consistant stream of diverse artists. And getting more into the indie rock relm with new releases from Bosco Delrey and Po Po.
