The ultimate 10-CD boxed set of Chiharu Matsuyama's live performances. 5 concerts that the artist himself is particularly fond of were selected and each concert is captured in 2 CDs. It is the first time a Japanese artist is making a CD boxed set out of live show recordings only. The initial 100,000 presses are limited LP-sized special box sets with LP-sized deluxe booklets. It's a set that fans that couldn't attend the concerts would love to have, and a valuable item for fans who actually went to the concerts.
