Last week, MTV posted a previously unreleased video of the band playing "Heart-Shaped Box" from the concert, and now they've unearthed two additional tracks: "Radio Friendly Unit Shifter" and "Very Ape," which features Kurt Cobain on drums. Watch the latter below.

Both clips are taken from rehearsal, meaning you get to see Cobain questioning his mic levels and tuning his guitar, as seen from one of many dazzling camera angles.
