IMO, it is impossible to hear/participate in/play music from other cultures, peoples, places and NOT be influenced by that experience. Musicians know no colour--the only things that really matter are the willingness to learn and the willingness to teach.

When I have questions about African music or culture, Azizi's the lady I ask. She's forgot more than I'm ever gonna know. And I thank her for sharing her knowledge so willingly.
