With tonight’s round 2 of Philly For Bernie Sanders concert at Boot & Saddle (which also features Tutlie and Tinmouth), the quartet of Son Step has released a fresh pair of songs to mark the occasion. “Mai Lai Wah,” which draws its title from the late-night, drunken-eats, Chinatown fave David’s Mai Lai Wah, slips into a mesmerizing, low-key, electro/synth, subtly percussive groove, washed over with the soft touch of vocal harmony. “Pink Knit” allows you to smoothly slip into time with the beat, pleasantly yet purposely paced to enjoy the ride. With their full-length, Natural Majique, due out this year, these songs certainly tease the ears.
