Formerly known as SPZRKT, Texas R&B songwriter Xavier Omär gained national attention in 2016 with his honeyed hooks on rap tracks by Mick Jenkins and Noname. But his talents come into full blossom with the beautifully innovative, emotionally rich R&B of The Everlasting Wave. “Lost in Nostalgia” floats like a daydream as he exposes his heart to a distant lover over aquatic synths, while “Speculate” showcases Omär’s vocal dexterity as he builds a multitracked chorus of hums, croons and falsetto ornamentations.
