A number of us went to the Surf Club to check out this "Belgradian 30-year-old female electric guitarist".
Ok, let's get the first thing out of the way. She is a striking little thing. That can't help but give her an edge. Beyond that she is fairly comfortable on stage. She was more relaxed than a native english speaker like, say, Mark O'Connor was last week. She speaks english very well with a trace of an accent. Musically Popavic is a very talented guitarist and she was backed by a really solid rhythm section. She listed a number of diverse influences, Steely Dan, T-Bone Walker, Stevie Ray Vaughan, Tom Vaits...er... Waits, Howlin' Wolf, and Ronnie Earl. But the music tended toward the Rock end of the spectrum. A lot of the music wasn't terribly danceable.
I suspect she is the big fish in the very small Yugoslavian Blues pond. And that may have caused a bit of a different evolution. Her playing was often very fast whether the song really called for it or not. The best description I can come up with is "Naive". She seems to be throwing in everything but the kitchen sink. For example, almost every song had at least one false ending. Which can be a useful little trick, but it was abused.
Navajo Moon is the first song on her website's audio loop is very much derived from Stevie Ray's Riviera Paradise. It was fairly well done. Her best was the closer, the blues standard, Let Me Love You Baby. She started fairly close to traditional, and showed some level of subtlety before unleashing the fireworks.
She's got the talent. But I think she needs a couple of years to mellow and age... and she could be really good.
