Definitely a classy well produced track. I dug it and it kept me company during my web activities for several cycles. I like the ambient keys a lot, they're layered really nicely and gotta love the quasi animal cry sound. Sounds like a classic d'n'b sample to my ears, Ray Keith 'Terrorist'? (I may be completely wrong!!!) nicely mangled and altered to fit the track.
The track develops slowly but convincingly, KB might have a point with the percussion. I never know though, plenty of tracks use a consistent percussion part and it works fine. Music does my head in sometimes! Man...anyway, bottom line..this is another fine track!
P.S 'pon de replay' means, 'play my track again' in Jamaican. I learned that from Rihanna, you know, SOS and all that? :) She's right up there with the Sugababes in my country!
