Jadranko Kerekovic aka Dubolik Originally from Sarajevo (Bosnia and Herzegovina), in early 90's he came to Zagreb (Croatia) and got in contact with ex-Yu punk/diy scene. For a long time he played the guitar in hc/punk band Radikalna Promjena. Over the years, his musical interests evolved and gradually went from punk to reggae to end up in dub and dub-influenced music.

In 2002 he participated in the founding of Radikal Dub Kolektiv, the first Croatian live-dub band. Soon afterwards, Radikal Dub Sound was formed, consisting of three Radikal Dub Kolektiv members. The project was conceived as a live act in digital, heavyweight dub style, where his role is mostly live dub mixing and studio production. With the band he recorded three albums. Meanwhile, he has been busy mixing and producing music with his fellow band mates for Radikal Dub Sound’s own material, as well as participating in other releases through collaborations, remixes, dub versions....

His current main occupation is a project named Dubble where he continues to work with former bandmate Vanja aka dr. Vax aka Vanya O, as well as a few other projects which include his mixing, production and dubbing. His interest in music production, loads of studio equipment and dub techniques continues to go in directions where no echo has gone before...
