The Strokes were joined on stage by Weyes Blood for a rare performance of their track ‘Modern Girls & Old Fashioned Men’. Check out footage of the moment below.The performance was held at the iconic Red Rocks Amphitheatre earlier this week and marked the New York band’s first show in Colorado in 17 years.Taking place on Monday (August 14), the performance was the indie veterans’ first in the state since 2006, and followed on from a series of live shows held across Asia, However, the night was made even more special for fans attending as Weyes Blood joined the band on stage, and performed a lesser-played track with them.The moment took place just five songs into their 19-track setlist, and saw the 35-year-old American singer – who was also the opening act for the band – collaborate on their track ‘Modern Girls & Old Fashioned Men’.The 2004 song originally appeared as the B-side to their ‘Reptilia’ single, and was released in collaboration with Regina Spektor.
