Ratchet (XL) Unabashedly gay and proudly androgynous, Shamir is a twenty-year-old singer and rapper whose macho drag bravado has not been popular since the days of Sylvester. His unconventional songs are built on jarring loops of early disco and house, with lyrics about volatile relationships on the rocks and a steroidal street swagger Shamir developed growing up as an unapologetic, black male fashionista in the rough neighborhoods of north Las Vegas. On the opening track named after his hometown, he vamps, “Vegas, we’re sinners all right, at least at night.” Known for his airy vocal stylings, Shamir proves himself an able rhyme spitter on the club-rap stomper “On the Regular.” On the breakup call to arms “Call It Off,” he soars over a slinky eight-bit video game beat with the neon-inflected sass of “Bad Girls”-era Donna Summer. Critics who dismiss Shamir as one more Ableton-enhanced voice floating over attractive dance beats would do well to listen to his recent cover of “The House That Built Me,” country singer Miranda Lambert’s earthy ballad about facing down childhood memories. A million miles from the dance floor, Shamir devastates the track accompanied only by an acoustic guitar and his own silky, world-weary voice.
