"Ruin" serves as a preview of the first Cat Power/Chan Marshall album in six years, Sun. If the cheery tone of "Ruin" is any indication of what's to come, Sun is an apt title. With its octave-jumping bass line and rushing percussion (that occasionally features a four-on-the-floor pulse) "Ruin" is the weird thing that happens when Cat Power goes disco (with the help of Cassius' Philippe Zdar, who mixed Sun). It's sleek, catchy as hell and Target-commercial ready. Could Sun be cleaned up enough to be Chan Marshall's Liz Phair? (That's if the critically acclaimed but relatively bland The Greatest doesn't deserve that title already.)
