Technical bassist IKUO has shown activity beyond genre boundaries, not only in J-POP, rock, and fusion with acts such as T.M.Revolution, BULL ZEICHEN 88, and The Choppers Revolution, but also by providing theme songs for popular anime such as "The Prince of Tennis" and "Yu-Gi-Oh! Duel Monsters GX." As 2026 marks the 30th anniversary year of his major debut, this becomes his long-awaited solo album for fans for the first time in about seven years. The concept of this work is clearly "all slap"! Moreover, it is an unprecedented 1000% IKUO world of "slapping continuously while singing"!! Here is the unprecedented destination reached by the bassist who has continued running since his debut. It also contains covers of T.M.Revolution, whom he has supported for many years, and SHINGOMAN (Agitato), who handles the sound production for this work.
