Boris Hrepić Hrepa is known to domestic audiences as a member of the well-known Split band Daleka Obala, which he founded with Marijan Ban. Less known is the fact that Hrepa started his musical journey as a blues musician. Given that blues was always part of him, the band Sunnysiders, with singer and guitarist Antonija Vrgoč, represents a return to his musical roots. Sunnysiders expanded with the arrival of new members, Goran Gubić Hans and Igor Paradiš.

Their set features original tracks, famous blues covers, but also songs outside the blues genre transformed to fit in with their rhythmic and melodic sound structure, which is distinctive for its two-part singing and the playfulness of the arrangement.
