Known for supplying an array of prominent Nashville artists with inventive pedal steel guitar parts, English musician Spencer Cullum further burnished his reputation as one-half of the eclectic instrumental duo Steelism. Throughout the 2010s, Cullum racked up loads of interesting studio credits with artists ranging from Deer Tick to Little Big Town while serving as a member of Miranda Lambert's band. His deeper influences -- surf rock, spaghetti Western, jazz -- became more apparent over his releases with Steelism, and in 2021 he fused his U.K. folk and prog rock roots with a Nashville studio sensibility on his first solo record, Spencer Cullum's Coin Collection. His second solo effort, 2023's Spencer Cullum's Coin Collection 2, was another powerfully atmospheric effort rooted in prog rock, British folk, and sunny psychedelic tones.
