Koco Ono was started as a favour to Emi because she wanted to sing in a band. Since her friends are so great and also very talented (ex members of bands like D.O.A and SNFU)they said sure, lets do it for fun!
And thats what it all is folks, good ol' fun punk rock cover band... with a never ending lineup change and long list of weirdness and a steady supply of beer!
