In May, Arlo Parks is releasing a new album, My Soft Machine, the follow-up to her 2021 debut Collapsed In Sunbeams. Over the weekend, Parks performed at the BBC 6 Music Festival in Cardiff and brought out some special guests. The xx’s Romy Madley Croft joined her to duet on “Black Dog,” and Fontaines DC drummer Tom Coll came out to play as a guest on the 2019 track “Sophie.”
