Perhaps Contraption: 'Twisted Brass, Avant Pop Marching Band'

Perhaps Contraption is a self-described "astonishing, twisted brass, avant pop marching band" from London.

The members are a mix of conservatory-trained musicians and musicians from the art rock scene.

Their unusual instrumentation includes a saxophone section, drums, French horn, piccolo, sousaphone and glockenspiel.

Nine members of the band were recently on their first U.S. tour, as part of HONK! Festival in Somerville, Mass., Providence, R.I., and New York, N.Y. The Honk Festival is an outdoor music festival of street bands.

"There's something really powerful about playing on the street acoustically, you can really connect with audiences," Charly Webber, the alto saxophonist told Here & Now's Robin Young.
