Haulix did an interview with Zack Zarrillo about his site PropertyOfZack. You can check it out here. The site will also be featuring interviews with Jason and yours truly in the coming weeks.
I just pay attention. If there's buzz or enough people recommend something to me, I'll listen most the time. We also take submissions for Showcases, and that's a great way to find new bands. We covered many more small bands in our beginnings, but slowly transitioned away from that due to demand. About two years ago we brought out Showcase to help smaller bands as best we could. It's been a success.
