Legend has it that in 1998 a man named Edgar Graham, a.k.a. "Ugly Casanova", impressed himself upon the band Modest Mouse while backstage at a concert in Denver, Colorado. After some prodding, he shared his work with the band, and began performing it early before shows while some people were milling around. Whenever he completed these performances, he retreated quickly with a look of anger and shame. After a time, a few small recordings were created, after which Edgar vanished completely.
So how cool is that? Apparently in actuality Isaac Brock made the guy up so that he could detach himself from the whole situation to avoid pesky interviews and such... but I still like to think that the story is true, if only because it is so eerie. The album is a great one, I was turned on to the band a few years ago by a friend who put some of the songs on a mix for me... I strongly recommend listening to "Things I Don't Remember," and "Hotcha Girls" for a good intro to the band. As far as side projects go, this one blows most out of the water, even though it is still not widely known. The music is mellow and the lyrics are trippy, good to listen to if you just feel like chilling out.
