The instrumental score to an idiosyncratic low-budget vampire flick, composed on Lennon's bedroom computer, Undead is dramatic and wild, sounding like the son of Ennio Morricone or Bruno Nicolai circa early '70s. Featuring Kool Keith and Miho Hatori (Cibo Matto) on the song 'Desire'.

Friendly Fire is the second studio album by Sean Lennon, released on 3 October 2006 by Capitol Records in the US, and Parlophone in the UK. It reached #152 on the US Billboard 200 chart and #5 in the Top Heatseekers chart.
