Hey rc, glad you're enjoying the BRK EP! Crushing The Wheat was released on the 2008 PDX Pop Now compilation CD, and given away online as part of the promotional push for the festival. You can find an MP3 here:

And you can buy the comp here:

The only other song on the myspace that's not on Furr or the BRK EP is Texaco, which you can find on the first BT album. You can find links for that right here: http://blitzentrapper.net/rexx.html
Thanks for caring about this stuff!
