Don´t listen to this stuff until you have enough time, pot or tiredness to be weird or just/even accessible to weird thing!
Here´s also the first song in live audio and picture if you´re more into seeing these things played live (even if it´s only on youtube...). But you can´t miss the second song off of the first link!
If you´re digging it check out more music of David Grubbs at meischbäss, läbelwebbseit (more easy to listen to) or jutiup:
You definitely should know/get to know Grubbs from bands like Gastr del Sol, Bastro or his several collaborations. I don´t know the other weirdos in the title above, so checkem out on your own if you like!
