The band pilvet pilvet consists of Kosti Koskinen (vocals), Touko Koivusaari (vocals, guitar), Onni Lehtinen (vocals, bass), Milan Marttiini (vocals, keyboards), and Kalle Karimo (vocals, drums). The band was formed when Kosti, Touko, and Onni ended up in the same class in middle school. The three were united by their love for music and, inspired by bands such as U2, Coldplay, and The 1975, they decided to form their own band in the summer of 2019. In high school, Milan joined, and the lineup was finalized last year when the current drummer, Kalle, joined the band.
