Music had been playing through one small speaker at a reasonable volume, local media reported, when it was interrupted by Carabinieri.
The police ban was met by confusion and hilarity from the guests, who reluctantly accepted the officers’ request, according to Italian news agency Ansa.
Oliva called it “yet another sign that a territory, rather than being valued and supported after a winter of severe shortages and neglect, finds itself penalised even in its moments of social gathering and visibility”.
Referring to the Mayor of Lipari Riccardo Gullo, she said “one would have expected a welcome to the guests, or at least a greeting and a thank you for their crucial contribution” to the local economy.
Stromboli is one of several Aeolian islands that fall under Lipari’s administration and are impacted by the mayor’s Wednesday music ban.
The BBC has approached Gullo for comment.
