Let's say you're a drummer, and you have seven mates who play brass instruments. What do you do? Cover Thrift Shop (by Macklemore & Ryan Lewis). Broken Brass Ensemble have three more demo tracks on Soundcloud, if you dig their mix of traditional New Orleans brass with hiphop, balkan, funk, fanfare, and more. Or you could just listen to a ton of brass band cover songs on YouTube, if that's you're thing.
In the United Kingdom, many brass bands were started by colliery owners, and funded in part by the coal miners themselves. Some of those bands live on, after the coal pits have been closed for years. These bands are facing hard times, with limited funding and waning interest in the music, but some youth join bands to continue family traditions, and the government provides some funding to numerous bands. If you'd like to know more about brass bands in the UK and around the world, Internet Bandsman's Everything Within (IBEW) has tons of material, links to bands in the UK and elsewhere as well as a list of extinct bands and vintage brass band pictures, local events and radio shows, recordings, and plenty more.
