U2: B-Sides
Apple Music
These lesser-known U2 gems show the Irish arena rockers experimenting with styles, as on the bluesy "Silver and Gold" and an extended EDM take on the '30s Cole Porter standard "Night and Day." But "Luminous Times (Hold On to Love)" stirringly reflects the band's mighty and majestic signature sound, while Robert Plant has called the hard-rocking "Salomé" his favourite U2 song.
