Adult Jazz is an experimental rock band formed in 2010 and based in Leeds, UK.

Members are Harry Burgess (vocals, lyrics, guitar, keyboards and sometimes drums), Tim Slater (keyboards and trombone) and Steven Wells (drums, guitar and bass), who all grew up in Guildford, Surrey before moving to Leeds for university. The three were joined by Tom Howe, who handles vocal effects, samplers and keyboards, as well as being the band’s producer.

They mention Van Morrison, Arthur Russell, Joanna Newsom and Meredith Monk as their biggest musical influences.
