The Lowdown: In the 20 years since Cat Power’s breakthrough fourth album, Moon Pix, Chan Marshall has lived many lives. The singer-songwriter seems to release an album every six years that marks major departures and transformations in her personal life. With 2012’s Sun, Marshall broke with cycles of substance abuse and stage fright, and she heralded the new era with synths, off-kilter dance beats, and even Auto-Tune. Now, with Wanderer, Marshall, 46, has parted ways with long-time label Matador and become a mother. As the title suggests, Wanderer is a name Marshall has adopted for herself, indicating that she embraces the unstable parts of her existence — rather than battle them so destructively. Wanderer gathers the inner depths and lonely instrumentation of Moon Pix together with the socially conscious, moody pop of Sun. For Cat Power, it’s still dark out, but there’s more to see and wrestle down the road.
