Hi, I'm David, from Seattle. My online identity is usually perceptualvortex, or perhaps Vortex, or PV.
I love mixing music, and most of my mixes can be found on my MacJams page:

And on my website:

It's super cool that these a cappellas are available for remixing. I'm almost done working on a remix of "All Lifestyles" and I'll put up a link when it's ready.
