[Machine Translation] This is a concept album that pursues the possibilities of a chorus group based on the theme of harmony. In addition to the new song "Natsu no Ame (tentative)" with a full orchestra in the background, a cappella re-recording of their debut song "Brightest Star," and re-recording of their distribution hit "Kirai...but I love you ~Aishiteru~," the album also includes songs that easily convey BRIGHT's appeal, such as "Kirai...but I love you ~Aishiteru~," a song that has become a hit in the past. In addition to songs that convey BRIGHT's charms in an easy-to-understand manner, the album also includes tie-up songs from Fuji Television's "Supokyun" TV commercial, "Flower" from the Fuji Television Flower Net TV commercial, and "Shining Star," the image song for the SHIDAX commercial. DVD includes 2 PVs and 4 songs from the 2010.3.27 Namba Hatch one-man live performance.
