If you're interested at all in the intersection of ghostly, leftfield music and beat-oriented pop, then you're probably familiar with Tri Angle. Since launching about a year ago, the boutique label has pretty well dominated this dark, ethereal corner of the indie universe, introducing or helping introduce about a half-dozen of its most intriguing artists (Balam Acab, How to Dress Well, Clams Casino, Holy Other). But if you think you've got Tri Angle pegged at this point, you may be surprised by its latest release, the debut EP from Fatima Al Qadiri, aka Ayshay. A New York-based singer and producer born in Senegal and raised in Kuwait, she makes digitally processed vocal music with an unusual global bent.
