Metales M5 is a Mexican brass quintet with a unique performing style. They were a huge highlight of recent shows as part of the Banff Centre "All-Star" Brass Ensemble Residency. Here, they talk with Evie Ruddy about getting together in 2005 in Morelia, Mexico as a “just for fun thing”, the conundrum they faced before they arrived in Banff this summer, and how the band's identity is changing. The conversation took place by the river, where the quintet enjoys rehearsing.
