Check out Zoe Keating. Especially if you're painting today. Her music is beautiful and haunting; perfect for getting into the creative "zone."
She's a cellist who uses a looping pedal to create the sound of an entire orchestra with one instrument. And it's not like she records the different parts first and then uses a computer to mesh them together. She can perform these songs live, using her right foot to add or subtract layers of sound.
I first heard about her on this episode of WNYC's Radio Lab, for which she occasionally contributes her music. That's worth a listen as well, since she explains the process and performs a couple songs.
