In 2000, the lead singer & Guitar Osamu Seino formed the band called Onepercentres with his 3 friends who have known each other long time and familiar in its local music scene. They have been influenced many kinds of music style and enjoyed playing music in styles of their own influences. At the first of their activities, they concentrated on writing their songs based on "power-pop" in the studio. And at that time, they had been focusing on their own feeling and their concepts to make their own POWERPOP even arrangements were not good though. It took quite long to have their own style of song composing, but it was not time wasting! They achieved they expected or even better! Know what!? They definitely knew and believe how good they could!! Then they thought it must be time to start playing in public, they started touring constantly and heavily! They released two MAXI-Singles and one single through their own label named Millionaire Recordings in four years. They were somehow pretty easygoing to record songs in studio.
In early 2004, the band teamed up with the one and only powerpop label called Wizzard In Vinyl then things were going much better than before. The first co-operation with Wizzard In Vinyl was distributing the mini album currently. The result was quite good since currently stayed in a chart of Tower Records for a while. Sometime in 2004, the original drummer left the band and the band got a new one called den den. In late 2005, they finally released the their first full length album named "PLATINUM BUNDLE". And then they went on tour with Swedish band called "Hawaii Mud Bombers" and Spanish band called "Suzy & Los Quattro". Both bands were blown away because of Onepercentres' live performances. After those intense tours, their reputation got much better! And also they got a Spanish deal. Now Onepercentres has been on the road to promote the album Platinum Bundle. This tour is planned to play 40 shows in about 4 months. After that, they'll go to Spain to tour in two weeks and play shows at the International Pop Overthrow Liverpool.
