It's nearing release day for the Black Keys'Turn Blue, so the guys took to BBC1's Maida Vale Studios to do a live session and premiere album versions of some new tracks - one of them was "Bullet in the Brain," which you can check out now. It's a great song - maybe our favorite from the record so far? - with a mutating backbone that shifts from blues to bass-heavy funk to rollicking psych-rock over the span of four thrilling minutes. And yeah, that's definitely the best bassline you'll hear today. Check it out - you can grab Turn Blue in a record store starting May 13th.
