Hypnotic Brass Ensemble are PHENOMENAL. I'm kind of a little obssessed with their music. I listen to their tracks while I'm running around London and it sublimely adds a musical texture to the cityscape. It has jazz roots infused with a hip hop sensibility, the band is made up of brothers from an extraordinary musical family. They've worked with artists such as The Roots, Mos Def, Erykah Badu and Damon Albarn. They've even had a documentary made about them. Peruse through the website, their music is great!
