"Gooey Butter Cake" is an uptempo swing composition by Japanese jazz trumpeter Jun Iida, featured on his 2023 album Evergreen. Named after the famous St. Louis pastry, the track is built on a 16-bar form in B-flat at a spirited 192 BPM, offering an exuberant showcase for the ensemble. The performance features three solos in succession: pianist Josh Nelson opens with two choruses of fleet, harmonically adventurous improvisation, followed by guitarist Masami Kuroki's two-chorus electric guitar solo that brings a contemporary edge to the swing feel. Iida himself takes the longest solo on trumpet, stretching across four choruses as the tempo nudges up to 195 BPM, building his improvisation with the melodic clarity and rhythmic precision that characterize his playing. The 16-bar form provides a compact but effective framework for each soloist, with the short cycle encouraging focused, idea-driven improvisation rather than sprawling exploration. Evergreen, released as Iida's debut album under his own name, showcases the trumpeter's dual identity as both a composer of original material and a versatile improviser comfortable in multiple jazz idioms. The album was recorded in Los Angeles with a core ensemble of musicians who bring a polished West Coast sensibility to Iida's compositions, blending modern jazz vocabulary with accessible melodic writing.
