Finland

Under a midnight sun that barely sets, Finland packs its entire festival season into a few incandescent weeks of summer. It starts in Helsinki, at the former Suvilahti power plant, where Flow Festival blends global headliners, adventurous electronic music and contemporary art in a cult industrial setting. But this is, above all, a metal superpower — nowhere on earth counts more bands per capita — and Tuska Open Air Metal Festival is its high mass, the weekend when Finland proudly celebrates what feels like its national sound.

Here festivals are bound to nature and memory: Ruisrock, set on the wooded island of Ruissalo near Turku, ranks among Europe's oldest, while Provinssi in Seinäjoki and Ilosaarirock, beside the Karelian lakes of Joensuu, have stirred the heartland for decades. Add the storied Pori Jazz on the banks of the Kokemäki river and the Nordic hip-hop hub of Blockfest in Tampere, and the spread is complete. FestT works out your FestiScore — how closely a line-up matches your favourite artists — and keeps dates, headliners and tickets up to date.
