City of Caterpillar is an American post-hardcore band from Richmond, Virginia, formed in 2000. They have released a split with Pg. 99, two studio albums, and a full-length compilation of demos and live tracks. Their songs, some of which are over 10 minutes long, are often characterized by melodic post-rock passages building up into chaotic outbursts.

Pg. 99 was a screamo band from Sterling, Virginia, a town on the outskirts of Washington, D.C., who are widely considered one of the pioneers of the screamo genre. The band formed as a six-piece in late 1997 and broke up as an eight-piece in 2003; at their maximum capacity they performed with two singers, three guitarists, two bassists and a drummer and were known for their intense live shows.
