CaptG - Sounds like you had fun jamming, keep me credited and you can keep it published on your SoundCloud if you like. My only advice on your tracks would be to focus it down, simplify and let the changes remain obvious. The chorus switch drowned out in your jam, as well as the turn around part and the simple middle part that's supposed to build back up in energy.
Wookie - You're absolutely right. I love the rhythm jam in that one, but it's not interesting enough on its own as a whole without an element of melody and lead to get your average non bass / drum playing person on board.
I've got a few tracks from SteveC to mix in, I'll have to post those to this thread later. If I had to describe the style element Steve is adding I'd go with early 80's Herbie Hancock. I'm still not sure that's where the final song will end up, but it sounds good for the style. I think this may end up with multiple versions online, like the Wogg version, the SteveC update... and whomever else I can coordinate with.
