Get an MP3 of Belle and Sebastian covering Dinosaur Jr.'s "Freak Scene" (and view a video of the band breaking into Van Halen's "Jump") at You Ain't No Picasso.

I remember the band covering "Gigantic" (it sent me into a huge Pixies spiral), but I don't recall this at all. It's eerie how much Stuart Murdoch sounds like J. Mascis.
Here's the cover of "Gigantic." It's really for completists only. Trust me.
Here's a much better Pixies cover:
And there are two much better Belle and Sebastian covers:
