Gavin Castleton performs a bedroom version of his "Sledgehammer" cover using Ableton Live 8, an FCB1010 midi foot controller, an M-Audio Trigger Finger, a Wurlitzer 200A eletric piano, and a Roland JP8000. All effects (including the vocoder which is being fed from a vocal delay aux send and the JP8000) are Ableton components. The audio was outsourced to another computer and multi-tracked for a much improved final mix (where some of the master cutouts were executed). Due to a total lack of budget (only 2 "cameras"), there are shots of earlier takes mixed in with the final take footage. There is a nod to Mos Def's "Do It Now" at the end.
