L-R: Arone Dyer and Aron Sanchez perform as Buke and Gase in November 2018. Each holds one of the band's titular, custom-built instruments: a baritone ukulele and a guitar-bass fusion. [credit: Sam Machkovech ] NEW YORK CITY—The band brings to the stage: two grids of foot-triggered effects pedals and switches; two music stands, covered with a smattering of synthesizers, touchscreens, and touch-sensitive pads; two laptops, connected to this variety of inputs in a center console; two stringed instruments, neither of which look exactly like a bass or a guitar; and two foot-triggered pieces of percussion. One of those is a compact kick-drum rig, connected to that array of laptops.
