Chances are, you already know Daytrotter. But in a series about excellent music websites, it’s almost criminal not to mention Sean Moeller’s extraordinary website. Since 2007, the site has been serving up excellent, intimate music sessions for the masses. Their motto: “One band a day, every day, 28 Daytrotter Session songs each week.” Here’s how it works: Bands take a couple of hours out of their travels to visit The Horseshack in Rock Island, IL., where they then record a variety of tracks. Daytrotter puts together some art, and an oft-amusing description of the session, and gives the music away on their site. It’s an amazingly expansive collection, too, and a true marvel that it’s all done in a not-for-profit enterprise. And while picking out highlights in this collection is like trying to pick out a favorite piece of sand on a pristine beach, I’ll do my best.
