Several months after first hearing it, some days I think Mirrorball is a collection of utterly beautiful music, other times I think it's a weird idea that doesn't quite come together as it should. Right now, listening to "Estrellita," I'm leaning towards the former. It's not what I expected, because I figured a Foxx/Guthrie collaboration would be instrumental, like Foxx/Budd and Guthrie/Budd, but it's got more personality than some of the interchangeable albums Guthrie's done in the last few years (and I say that as a longtime Guthrie fan). And after the Louis Gordon collaborations, it's nice to hear John actually singing.
