As a follow up to “Worth It” from last month, Los Angeles-based crooner Moses Sumney rounds out September with “Lonely World,” bringing along Brainfeeder bass virtuoso Thundercat into the mix. The single begins at a mellow point, with rippling electronic keys rising to be met by Thundercat’s dissonant bass arpeggios – the ethereal, ominous tone on Radiohead’s “Decks Dark” from this past May’s A Moon Shaped Pool comes to mind. Enter Sumney. He initially gives a breathy, light vocal performance, but as instrumental grows in body – an assortment of percussion, horns and backing choirs – Sumney soon after projects his falsetto over and through mountains and valleys of soundscapes. It’s beautiful and awe-inspiring to say the least.
