Inside Seaside

Poland / November 8-9, 2025

Description

Inside Seaside is one of the few significant indoor events with a music program that take place in Poland during the fall. It’s a two-day celebration of music in the specially adapted halls of AmberExpo, where, for two days, the top of the Polish and world electronic, rock, and jazz scene performs on three stages

But that’s not all: festival participants are able to make themselves comfortable in the cinema of Radio 357; silent disco sets will be played by female and male journalists from Radio 357, and there will be meetings and discussions, a food court and a relaxation area, as well as themed zones. Their visitors can spend the weekend in a space buzzing with music and non-musical attractions.

Inside Seaside is organized by Agencja Live, with many years of experience in producing significant cultural events such as Żywiec Męskie Granie, but also T-Mobile Electronic Beats, Sea You Music Showcase, Mata Tour, SBM Festival, Fryderyki, Zalewski MTV Unplugged or Wodecki Twist.

The festival is co-created by the team of Radio 357, the most popular internet radio in Poland, funded by the listeners.
