I just saw Maneskin last weekend at Rock for People festival in the Czech Republic. They got huge really fast and definitely the a band for gen z, so they could easily replace MGK.
Half of the setlist were covers, their hit song was played 3 times (normal, Iggy Pop version and as encore)... the kids loved it (actually not sure, if they know the original songs except Harry Styles or billie eilish covers)... nothing special about the band.
Good thing is, that many kids came to the festival to see them and left with better bands to listen.
