METALLICA's concert Tueday night (July 16) in the southern Finnish city of Hämeenlinna was attended by 55,000 people — about one percent of the country's total population. Ahead of the sold-out gig, the band donated 55,000 euros to the Finnish children's charity Hope Ry — one euro for every member of the audience.

All four members of METALLICA met with the charity organization before their concert, to learn more about their work which involves distributing clothing and other essential items to children in need, or families going through a crisis.

Eveliina Hostila, executive director of the charity, told Ilta-Sanomat that the money will be used to support the hobbies of over 200 children for a full year.

METALLICA's set included a Finnish-language song. Bassist Robert Trujillo and guitarist Kirk Hammett performed a cover of "Kuuma Kesä" ("Hot Summer"), originally written and recorded by the Finnish rock band POPEDA.

The Hämeenlinna concert was part of METALLICA's "WorldWired" tour, which has played more than 130 shows across the world since its 2016 kick-off.

The San Francisco Bay Area metal giants have been touring in support of their latest album, "Hardwired… To Self-Destruct", which came out in November 2016.

Last November, drummer Lars Ulrich told The Mercury News that the trek could last through early 2020.
