Fat adj. Full in tone and quality. Quarter (note) n. The underlying pulse of groove. Fat Quarter serves luscious jazz, offering their take on less-known hard bop and soul jazz tunes, along with Latin and funk groove-based reinterpretations of jazz gems…and a side of original composition. Fat Quarter is led by drummer Gaby van der Velde with Lazar Miric on tenor saxophone, Josh Smiley on piano and Hiro Tanaka on double bass.
