"Mauna Loa" is is one of my favorite songs to play. It is based on Ozzie Kotani's arrangement from his instruction book (and is uploaded with his permission).
This version is recorded on my Rainsong OM1000 direct into a Fostex MR-8 digital recorder. It's the hidden bonus track on this year's Taropatch CD set!
Tuning: Taro Patch
