this is a good start. I find the groove nice, but at the same time a tad repetative....and I can understand that some vocals on top of this is what is probably needed. This would make GREAT dance music on its own, but lacks a bit musically just to be a "listener". HOWEVER>..and a big However....this tune takes off in a completely positive direction when the pno soloing comes in. INCREDIBLY MUCH BETTER....at least in my book. Really tastefull soloing, and the tune becomes much more interesting musically. Great chops....(but remember, the TWO CHORD change keeps this 'dance music' which I acknowledge you stated...but it has the potential to be MUCH more, imo).
I like this very much.....and I'll be eager to hear how you finish it off. (I'd love to put a killer lead gtr on this too)
the mix sounds good so far, EQ wise, etc.... a little sloppy on the ending....
