長尾大
"Tao" became Do As Infinity's twentieth single released on July 27, 2005, and the last before disbanding later that year. The lyrics of "Tao" described about friends parting ways and this caused many rumors among the fans about the disbanding of Do As Infinity. "Tao" was also the main theme of "Tales of Legendia", an RPG released in summer 2005 and developed by Namco. The band announced on September 14 that they would disband on September 29, 2005, just six years to the day of their first single, "Tangerine Dream". Their last concert was at the Nippon Budokan on November 25, 2005. Three days before the final concert, Dai Nagao released the last Do As Infinity song called "Trust" on the official website through Internet streaming. The vocals featured in this song is sung by Mizushima Kana from one of Nagao's side project artists I-lulu.
