They are hand's down the best brass band I have heard outside of New Orleans. And while they are hugely inspired by the music of that city, the Brass Street Boys are also influenced by Balkan sounds and Spanish-language rock of the 1980s. But what they do is unique. I am still trying to figure out how a group of Mexican kids this young (one of the sax players is 18, and the oldest in the band can't be more than 25) have come up with a sound this original. They are playing this coming Tuesday the 27th at the Pata Negra (Tamaulipas 30, corner Juan Escutia, Colonia Condesa) at 9 pm. If you can't make it, follow them on Facebook, where they announce all their gigs.
