Hi Chris,
First of all…I am Polish! That’s right. I’m 3rd generation in the USA and don’t speak a word of the Polish language but both of my parents are Polish!
As for seeing the Berklee Marley ensemble, go to the art of reggae youtube page and scroll all the way down (after hitting ‘videos’). There’s some there. Also just youtube search ‘Berklee Bob Marley ensemble’ and you’ll find a bunch.
There’s this one as well: https://www.youtube.com/watch?v=ivBg3C-U82c
Enjoy!
Matt
