History: In April of 2002 the four of them formed a band, Primrose, and despite their youth, they actually gained a bit of success. Two years later they changed their name to Soroban, and on June 17th they had their first performance as Soroban at the Ikebukuro Cyber. At this performance they distributed their first single, “Shirokuro Radio” for free.
On October 6th, after performing at various events, Soroban went on their first one-man at Akasaka Ian, which had sold out. “-RAM-/Orange Tegami” was released on November 1st, and ranked 7th on the Oricon charts.Soroban signed to Danger Crue and started Sky Crue records, their own sub label.
They released a mini album and three singles in 2006, which were followed by promotional performances.Shortly afterwards, Soroban announced that they would disband in August, and their last performance together would take place on August 2nd .
Opinion: There’s barely enough music for me to use for an opinion, but if they stayed together I just know they could’ve become one of the big boys in JMusic.
Singles: Koudou Gestalt, Ginrei Hydration, Kinmei Nouzenharen
Mini Album: Gekisai Chappuru
