Just got back from Musikfest, in Bethlehem PA, and got to catch a set from Freekbass. From the photos on the Musikfest website I was expecting something Les Claypool, but what we got intead was more like Bootsy Collins. In fact, Freekbass bills himself as a Bootsy protoge, they have worked together.

Quite an impressive set of spaced-out funk; lots of fun. Freekbass had two nearly identical custom instruments. They looked very cool, and very comfortable as well. Unique body shape, maybe a Chinese character? or maybe just something made-up. Couldn't find any info about them on the website, but there are some pics.
And of course, the envelope follower was on all night long
