Adults are the original project of Igor Spolski and Karol Strzemieczny. The musicians, faithful to the idea of DIY, took on not only writing new songs, but also the whole process of registration and production. The work on the album took place in their own portable studio, and the result is a short playing album Dorośli. The premiere took place in autumn 2019. The line-up of the band is completed by the cellist and vocalist Iza Lamik.
