Mac McCaughan, co-founder of Merge Records and frontman of the band Superchunk, began recording solo albums under the name Portastatic in the early 90s. Beginning with this album, Portastatic evolved from a lo-fi side project to become McCaughan's main focus throughout Superchunk's long hiatus in the early 00s. Recorded in Chapel Hill NC, the Summer of the Shark included contributions from Janet Weiss (Wild Flag, Quasi, Sleater-Kinney), Tony Crow (Lambchop), Margaret White (Versus, Matt Pond PA), Matthew McCaughan (Bon Iver, Hiss Golden Messenger), Aaron Oliva, and John Plymale.
