You've got to love a band that marks fifty years by going back to school and playing surprise gigs on Dublin street corners. There's something rather touching about U2 returning to where it all started, especially given how monumentally they've shaped rock music over half a century. The nod to Glen Hansard as well shows they haven't forgotten where the Dublin music community comes from, which is the kind of thing our listeners appreciate when artists remember their roots. Whether you're into their stadium anthems or prefer your music a bit more stripped back, this kind of homecoming celebration is the stuff that reminds you why rock and roll still matters.
