Classically trained composer, multi-instrumentalist and singer Imogen Heap finds her muse in unlikely places. She's mined sonic mystery from sources ranging from cardboard tubes to cheap samplers to the data gloves--not to mention her own vocal cords.

A relentless experimenter, Heap's latest song cycle is built around some 900 fan-submitted "sound seeds," or samples of everyday sounds. The first six of these "Heapsongs" have been released via her website, and include the lovely "Propeller Seeds," inspired by a chance meeting at a past TEDGlobal. During 2012's TEDGlobal she recorded a song in various locations around Edinburgh, "anywhere that has a piano and they let me turn up with a microphone." She has also composed the orchestral score for the crowdsourced nature film "Love the Earth."

Heap's last album Ellipse earned her a Grammy and Ivor Novello award. This summer marks the release of Sparks, her fifth and most ambitious album to date. Sparks' songs have taken Imogen all over the world from her North East London home studio to the Himalayas via China. This year Imogen is the guest artist-curator for the iconic London Roundhouse venue’s new music festival, Reverb. The eagerly awaited Sparks world tour will begin at Reverb in August 2014. Meanwhile, Imogen will be celebrating her tenth TED anniversary this year.
