Heap, Imogen: Hide And Seek (SATB) Novello Choral Pops series  

The recording of this hauntingly beautiful song features Imogen Heap's voice and the harmonizer which is used to shift vocal patterns pitches to create an a capella effect. The song was heavily sampled by Jason Derulo in 2009 for Watcha Say, an R&B style song which also achieved international success. The layered vocal style is translated here into SATB a capella.
