Jay Z and Beyoncé showed up to the Grizzlies' Brooklyn Waterfront show last night and set the New York arm of the twittersphere ablaze. Today Grizzly Bear should retain some of that heat by releasing the single for what is one of the year's as well as their back tracks: "While You Wait For The Others." But wait, this is going somewhere. The single's B-Side is only a version of the song featuring the inimitable Michael McDonald. SONIC COLOGNE.
