Prog & Rock, an event dedicated to Polish bands exploring the rich heritage of progressive rock, will come to Elbląg's Mjazzga; Euphorizone, Oudeziel and The Broken Bridges will perform there.

Euphorizone is an instrumental and vocal portion of rock music mixed with the progressive inspirations of the group's co-founders. Melancholy and art-rock fantasies with the indispensable participation of keyboard electronics, in the frame of dynamic rhythms create a horizon of words and sounds on which a group of passionate musicians found themselves, creating together their own zone of sound. The band was formed in September 2016 in Gniewkowo. In late 2022 and early 2023, it recorded its debut album in the studio. The album, entitled Invictus, was released in May 2023.

The Broken Bridges are a prog rock band from Grudziądz, Poland, formed in 2014 by guitarist, singer and sole songwriter Marek Habryn. They released their debut EP Endless Road in 2019; they are now working on their second album. The Broken Bridges currently consists of Marek Habryn (vocals, guitar), Grzegorz Grzanka (keyboards, accordion), Łukasz Dryl (bass) and Slawomir Kaligowski (drums).

Oudeziel play instrumental prog rock and comprise Artur Wolski (music writer, guitarist and keyboardist) and drummer Jarosław Bielawski. At concerts, the band is supported by other invited musicians. The composers used to form the band Obrasqi. The band's musicians have performed at many concerts, festivals and in radio studios with Eivor or RPWL, among others. They also played as a special guest on the finale of Riverside's anniversary tour, and as Oudeziel as a special guest of the Collage tour. In 2023 their debut EP was released by Dutch Rock Company.
