Samba - a taste of what I've recently gotten involved with

I've joined a Samba troup - Calgary Escola de Samba. Here's a video of our most recent performance. The percussion instrument I was playing here is not what I usually play, but I am still learning the different instruments. Who knows, this might become 'my instrument', although there are other instruments I like as much or more. So far, I've most often played a surdo - the big bass drums that are at the back. I like the sound of the surdo and the upper body movement involved. We usually strap it around my back and rest the drum on my wheelchair foot rests.
