These youtube videos are one of the last performances of Masa and
Hiromi as Kokin Gumi.  They are at the 2007 Matsuri in Phoennix, a
venue and festival they had played many times in the past.

Their Tsugaru Shamisen player, Tateo Takahashi, died in 2006, and
in these videos Masa is suffering from cancer as well.
