That's probably because it's in Japanese
"T-SQUARE alpha" started its activities as a unit form of Takeshi Itoh and Satoshi Bandoh 44 years after his professional debut in 1978. The name T-SQUARE alpha has the meaning of plus alpha that something is added freely to the next. This album has wonderful support members and guests who deserve such a name. Japan's world-class top jazz guitarist Kazumi Watanabe (Gt), ally Hirokuni Korekata (Gt), Masato Honda (Sax), who will participate in T-SQUARE for the first time in more than 20 years, and Keiji Matsumoto ( Key). Furthermore, as Japan's top horn section, Eric Miyashiro (Tp), Koji Nishimura (Tp), Eijiro Nakagawa (Tb), Nobuhide Handa (Tb) who lead the Blue Note Tokyo Jazz Orchestra. Rock-solid support members indispensable for T-SQUARE Shingo Tanaka (Ba), Akito Shirai (Key), Yudai Sato (Key). In addition, there are already a lot of great young musicians in attendance. There is no doubt that this album, in which the top musicians in Japan are participating, is suitable for the new T-SQUARE! Comes with a Blu-ray (contents undecided).
With all that translating, JP, I was referring to the contents of the included BD~V ..... which at the end clearly states "Contents Undecided" .... Is it a concert video or a BD~A containing the album in 5.1....or both?
