Portastatic is an American indie rock band founded in the early 1990s by Mac McCaughan. Portastatic began as a solo project for McCaughan, lead singer and guitarist of the indie rock band Superchunk. Since then it has evolved into a full-fledged band, which sometimes includes Superchunk guitarist Jim Wilbur and McCaughan’s brother Matthew.
Tom Scharpling of 18 Wheeler fanzine (and later a popular DJ on WFMU) was so impressed by McCaughan’s solo material that he cajoled him into releasing it under the fanzine’s own imprint; so came 1993’s "Starter" 7". Since then, under the Portastatic moniker, McCaughan has recorded several records drawing on a number of genres, including traditional indie rock, lo-fi, soundtrack and Brazilian music.
The name "Portastatic" is derived from the TASCAM Portastudio home recording device. Due to the quality of the recordings, Mac McCaughan added "static" to "porta" to form "Portastatic."
