Don Caballero Reunite With Y2K-Era Lineup, Add 2027 Primavera Sound Date

Pittsburgh instrumental group Don Caballero are reuniting, according to a Stereogum interview published October 5, 2026. The band, which helped define math rock during its original run from 1991 to 2000, is coming back with its Y2K-era lineup rather than its founding 1991 configuration — and already has a busy 2027 calendar lined up, including a stop at Primavera Sound.
What was announced
The reunion features the band's turn-of-the-millennium lineup, including bassist Eric Emm, rather than the 1991 original lineup. Members reportedly had already been preparing for the 2027 dates in the weeks before the announcement went public.
- Lineup: Y2K-era configuration, including bassist Eric Emm
- Confirmed show: Primavera Sound (2027)

The Stereogum interview took place at Emm's home in suburban Connecticut, where band members swapped stories from tours a quarter-century ago.
Why it matters
Don Caballero were central to math rock's emergence in the 1990s, known for vocal-free instrumental lineups, complex time signatures, and jagged, start-stop rhythmic structures. The band went inactive after 2000, and this reunion answers a long-standing ask from fans of the genre.
