Could you help me discover the name of this band?

I was in New York City this morning. At about noon on Times Square, this interesting street band started to play. Ethnically,they were (probably) Central or South American Indians. There was a drummer, a guitar player, an eight string mandolin player [?], and two guys that played pipes. A girl was selling CDs. I stopped and listened. I thought about buying a CD, but I was in a hurry, had little cash in my pocket so I moved on.

Now I regret not buying a CD. The music was pretty cool.

I will recognize the name if I hear it. It was printed on their instrument cases.
Do you know who I am talking about?
Thanks.
