Poppy Ackroyd is a British composer, pianist and violinist and a regular member of the live project Hidden Orchestra.

She is known for her "non-conformist approach to producing sounds"[1] and while her debut album consisted of violin and piano played by Ackroyd, Resolve, incorporated improvisation from Manu Delago, Jo Quail and Mike Lesirge.

Feathers, her second album, followed in November 2014 and builds on the concept behind her debut, with most of the sounds again coming from the violin and the piano; however, this time the tracks also feature other keyboard and string instruments.

In 2017 she signed to Björk's label One Little Independent Records and released a mini album, Sketches in August.

Resolve features guest instrumentalists for the first time including Manu Delago on hang, Mike Lesirge on flute and clarinets, and Jo Quail on cello.
