You won’t feel comfortably numb when Pink Floyd tribute band the Machine rock your socks off at Strand Center for the Arts in Plattsburgh, N.Y. The New York quartet continues the legendary English group’s psychedelic grooves with masterful renditions from its space-rock canon. Listeners float to the dark side of the moon as the band passionately performs iconic hits, as well as lesser-known tracks hidden within Pink Floyd’s 16 studio albums. Elaborate theatrical elements, expert stage displays and heady lighting conjure the spirit of the ’70s and ’80s to complete the intoxicating experience.
