Being independent is admirable, but it’s what you do with that independence that defines your work. Erin McKeown seems to know this. She is an independent artist in the truest sense of the word, especially now, as she strikes out on her own with her self-released seventh album, Manifestra. What Erin has done with her independence over the years is to experiment with musical genres (folk, jazz standards, pop, rock), mixing and matching them as different vehicles for delivering her always-smart, honest lyrics, and therefore defying easy categorization. Manifestra is a statement-making album, as the title implies. There is strength and intelligence running throughout, and has the unique quality of both having important, relevant things to say, yet, musically, it goes down easy. Manifestra is so enjoyable, interesting, playful, and even buoyant, that you want to know what Erin McKeown has to say about politics, the death penalty, and economic inequality. Hear Manifestra in its brilliant entirety tonight at 8, as the WFUV CD of the Week, on 90.7 FM and wfuv.org.
