Marateck has been referred to as a “math rock” band, and fittingly so; their entirely-instrumental music is a line graph of crescendos and decrescendos joined by smooth bell curves at one moment and jarring minimums and maximums the next. The experimental four-piece is string-based, consisting of a family of guitars (standard, bass, and baritone) outlined by sharp drum staccato. Guitarist Brendon Randall-Myers is a Yale School of Music graduate whose repertoire includes work with operas, symphonies, and theater groups in the US and abroad. Marateck’s first full-length, which awaits release, will feature amped-up versions of songs from 2014’s EP, which was recorded as a three-piece. Local noise rockers Swindlella will open. The band features Cloud Nothing’s Jayson Gerycz on drums and Chris Brown on guitar. (Bethany Kaufman)
