BTTB is a 1999 piano solo and duet album by Ryuichi Sakamoto. The album title is an acronym for "Back To The Basics". Two separate versions of the album were pressed, for Japanese and international markets. The International version opens with the three songs off of the maxi single released in Japan as a promotional tool, while replacing a few pieces elsewhere in the album. The maxi single peaked at no. 1 in the Japanese singles chart and was the fourth best selling single of 1999 in Japan.[1]
