It's an unusual week; I don't know many of these acts. Janine and the Mixtape is a big name here, but aside from that I couldn't describe the music further.
The "not that new" section is a bit more recognisable: Ghost Wave are very popular.
Jocee Tuck plays some pretty nice acoustic stuff.
Plastic Paco was on the show a few weeks ago, and plays a strangely fitting blend of ambient and country.
I would, however, highly - and I mean HIGHLY recommend checking out the podcasts, or, at least, Mali Mali's. The guy is a good friend of mine (for a writeup check out my blog and the podcast is a really really nice one.
