Hmmm, nice!

Excellent production and mixing, tho I dunno if I'd call it electro, to be honest. Something about the drums says "Roland R8 MKII" to me, and I always associate electro with stuff like the Korg ER-1, blippy 8-bit, and lo-fi analogue. When you say vocals are going to be added, I think more EBM gothy darkity-dark stuff. I haven't heard any of your other works yet, so I'm going from 100% initial impression.

I love that swoopy half-bar sub-bass filter thing you've got going on - bet that'll sound great in a club! I could easily see myself getting a little drunk and totally grooving to this.

Actually, I've got the voice of the guy from Korn stuck in my head - 'Freak On A Leash' is in my playlist for god-knows-what reason this week, and I bet that style would fit really well right over top. Trent Reznor-ish. I look forward to hearing where you go with it.

I hear a really great techno/EBM extended remix buried in here.
