ALexander Suarez Mendez is one of a group of pipers from Cuba, nurtured by an outreach program of Na Piobairi Uilleann. He's been brought over to Ireland by NPU a few times, as was Rosalia Acosta Corrales.

There are uilleann pipers of many nationalities and ethnicities.

I am not sure what your reason for singling out a black piper is, there can be an element to this that makes me uneasy sometimes. I played a concert a few years ago where Alexander also appeared. After the concert finished I was talking to a friend, also a piper and as it happens black, a woman came up to congratulate him on his piping (thinking he was Alexander), saying something along the lines of 'it's great top see you guys doing so well on the pipes'. I know, it's meant well, but really?
