Dua Lipa played stripped down versions of four tracks from ‘Radical Optimism’ for NPR’s Tiny Desk series this week – check out footage below.On Friday (October 25), the singer gave intimate performances of ‘Training Season’, ‘These Walls’, ‘Happy For You’ and ‘Houdini’, with gentle piano, acoustic guitar and glockenspiel backing. At times, Lips picked up the pace, enhanced by electric guitar and backing vocalists, but it was the closeness of the setting that set the session apart.“I’ve always wanted to come down and be by the desk,” she said.
