The mercurial neo-psychedelia of GUM is the creation of Pond and Tame Impala drummer Jay Watson. The solo project's full-length debut, Delorean Highway, appeared in 2014. Taking a varied approach over the next several years that was always trippy but sometimes drenched in fuzz, more robotic synth pop, or crunchier rock, GUM went with synth-enhanced psych rock for his more cohesive fourth album, 2018's The Underdog. The palette-shifting but consistently cosmic Out in the World and Saturnia followed in 2020 and 2023, respectively.
