这部作品是由来自静冈县伊东市的说唱歌手OwlBoy与DownTownDogs的SEEK合作创作的。SEEK比OwlBoy小两岁，他受到OwlBoy的作品《El Chapo》等曲目的启发。在两国的录音室中，双方互相聆听对方的歌曲后，决定共同创作这张专辑。正如EP的标题所示，这张专辑包含四首曲目，适合在夏季或秋季的漫长日子里随时聆听。 This is a collaborative work between OwlBoy, a rapper from Ito City, Shizuoka Prefecture, famous for its hot springs, and SEEK of DownTownDogs. SEEK, who is two years younger than OwlBoy, was inspired by OwlBoy's work "El Chapo" and other tracks, and after listening to each other's songs in recording studios in both countries, the two decided to create this album. As the EP title suggests, it contains four tracks that can be listened to all day long, depending on your mood, on a day when the days are still long in the summer or fall.
