Vision and devotion collide when Interpol opens for Morrissey and many great and singular pop songs emanate into the great beyond that is nostalgia. Nostalgia in its rawest form, aching and yearning and possibly unfulfilled. As such, Morrissey will play assorted hits from his preposterously unlikely career, as well as some of the covers he’s recorded on this year’s California Son LP. Songs like Jobriath’s “Morning Starship” rub elbows with “Loneliness Remembers What Happiness Forgets” by Dionne Warwick in characteristically head-spinning turns courtesy of Morrissey’s prodigious ear for good songwriting. Interpol remains Interpol, as evidenced on this year’s A Fine MessEP, a record comprised of tracks they left off of last year’s Marauder LP. And the fans remain the fans, because when music hits you, you actually do feel a pain — something that only music and nostalgia can succor.

Morrissey and Interpol play at 7:30 p.m. on Saturday, October 5 at FivePoint Amphitheatre.
