That's a pretty cool song and the band influenced others, especially Kurt Cobain from what I hear. I think he once said Smells Like Teen Spirit was his attempt to make a perfect Pixies song. And now bands like The Orwells are sounding like Nirvana, so the influence propagates.

I think I hear a Theremin in there. That electronic instrument was used in few Garage Rock songs. I think I'll post one soon on my blog here!
