It’s always difficult when the people who founded a band — who founded anything, really — break up. Oft times, it signals the demise of the band, as they realize that the need for full separation outweighs everything else. Other times, though, they soldier on, which is what happened with Superchunk as singer/guitarist Mac McCaughan and bassist Laura Ballance broke up as Superchunk was working on their fourth album, 1994’s Foolish.
Honestly, I have no idea what happened: they were a couple. They founded Superchunk. They founded Merge Records. They broke up, and both Superchunk and Merge Records remained going concerns. Everything else would be speculation on my part, up to and including whether or not any of the songs on Foolish and the subsequent albums were about the breakup, though Ballance has discussed how difficult it was to tour Foolish.
