Uprights and EPs is a stack of 11 of our favorite vintage electric and upright pianos. We hammered the strings, we added felt to the upright, we put overhead mics on electric keys, we left one piano a little out of tune, and we even sampled the chorus on one of our favorite old keyboard synths. Fender Rhodes, Wurlitzer 200A, Yamaha CP 70-B & CP-30, and more.
