Free Primo Maggio concert in Rome on Tuesday 1 May.

On 1 May every year Italy dedicates a public holiday to its workers in celebration of the Festa dei Lavoratori.
The national holiday is marked in Rome with a large, free May Day concert in Piazza S. Giovanni in Laterano, which will cause numerous street closures in the area throughout the day.
Organised by Italy's main trades unions, the annual Primo Maggio "concertone" is now in its 28th year. Starting at 15.00, it runs until around midnight and is broadcast live on Italian tevelevision channel RAI 3.
The 2018 concert has a diverse line-up including Fatboy Slim, Carmen Consoli, Gianna Nannini, Max Gazzè, Le Vibrazioni, Willie Peyote and Lo Stato Sociale. For full details see Primo Maggio website.
