Recently I have come across a singer/songwriter/didgeridoo player from Australia. Xavier Rudd. Surprisingly enough my mother-in-law was the one who found him (I am not sure where) and really liked his voice. I have checked out several albums now and I find it to be quite alluring. There are a few songs here and there that are on the "so-so" side of my taste, but most of it is quite simple, lovely, and of course when that didgeridoo gets going... well that is just good times. So if you are in the mood for some new music on the side of a more popular idiom check him out, (he has some albums on Amazon, as well as Half.com) because sometimes you just have to put the John Cage to the side for a few days.
Here is a nice video of him in the studio from his first album To Let:
