With TJ of Hachi & TJ busy with Ukulele Picnic, Hachi has had to find himself another collaborator. He did so in Eri, and the ukulele playing duo released its first digital single, 차라도 한 잔, on July 28. The first full length album, 꽃들이 피웠네, will follow already on August 4 and includes the single title track as well as the other song off the single, 무지개색 빛.
