I wish I paid closer attention to artists' non-industry activities. unbeltipo is a three-man lineup including Tsuneo Imahori (listed as the band's composer as well as guitarist), Mitsuru Nasuno on bass, and Yasuo Sano. These three are contemporary legends. The style of the music is influenced by Imahori's former band, the revered Tipographica.
Anyway, the three of them should have unbeltipo added to their "Units" sections. unbeltipo does have a number of albums out as well. I'm going to be looking into importing them and can add and scan.
EDIT:
Just thought I'd share a sample. You're welcome. Now buy their stuff.
