Atlanta’s Collective Soul, pictured, burst forth from the alt-rock school of 1993 with their monster hit “Shine,” following it up in the mid-’90s with orchestra-backed songs such as “December” and “World I Know” that would become radio favorites. 3 Doors Down’s first hit, “Kryptonite,” was released in January 2000, followed two years later with fist-pumping tribute to military servicemen “When I’m Gone” and ballad “Here Without You” from album Away from the Sun. Together the bands span two decades of radio hitmaking, which they’ve combined for their co-headlining Rock & Roll Express Tour.

Both bands formed in the South and have remained together continuously through good times and bad. Collective Soul–fronted by singer Ed Roland and featuring original band members Dean Roland and Will Turpin–was pleased enough with recordings of concerts from recent years that they released a live album in December, aptly titled Live. Mississippi’s 3 Doors Down, with founding member Brad Arnold on vocals, released a sixth studio album, Us and the Night, in 2016. The two acts are trading off headlining sets during the summerlong tour, demonstrating their durability in a music industry where streaming pays peanuts and having built a brand yesterday ensures success on the road today.
