On December 13, 1993, Nirvana filmed a concert at Seattle's Pier 48 that was aired on MTV as "Live and Loud". That special is getting a DVD release tomorrow alongside the 20th anniversary In Utero reissue.

Today, MTV and VH1 have shared two never-before-seen rehearsal videos of the band performing "Very Ape" and "Radio Friendly Unit Shifter". "Very Ape" features Kurt Cobain playing the drums.

Watch both below.

And remember, tomorrow, you can also get your free Nirvana tattoo.
