Formed in 2014, the band grew out of the solo endeavors of singer/guitarist Jack McEwan. Working out of an old horse barn in rural Leederville, he and fellow guitarist Luke Parish, bassist Luke Reynolds, and drummer Danny Caddy pooled their collective consciousness in massive all-night jam sessions, developing the musical conversations that were honed into 2016's High Visceral, Pt. 1. A sequel, High Visceral, Pt. 2, appeared a year later and doubled down on the band's fusion of bluesy riffs and experimental yet melodic guitar rock. With their profile increased thanks to international touring, the Crumpets took a harder-edged approach on their 2019 outing, And Now for the Whatchamacallit, an album which also featured some of their most intricately structured psych-pop to date.
In October 2020, the band announced their forthcoming 4th LP SHYGA! The Sunlight Mound, due to be released 5th February 2021.
