I am recommending one of my favorite Modest Mouse songs today. Actually I am going to recommend two songs by them.
I Came As A Rat - Modest Mouse - The Lyrics are great, complicated, but delivered with such speed, in a way only Modest Mouse can. The guitar work is brilliant, and works well. It may have pretty bad production, but it adds to the song in a way.
Shit Luck - Modest Mouse - This song is more instrumental (Beside a few shouted lines) but it has impressive guitar skills throughout and is a good heavy romp!
