Hi bros how r u.

I was just wandering if one of you could tell me wich sample was used by Liam in the first Unstoppable version (the reggeametalpunk version on youtube). We can hear some hip hopish voice saying ''Blow your head come on'' or something like that several times before the beats come in. Have searched the forum and found no lead. Sorry if its a repost. can someone help plz?

thx in advance
