It's a typical rock move: there are countless examples of groups where the fans stand up and scream for the classics, then sit on their hands for the new material that just can't hold its weight in comparison to past brilliance.
Copper Blue rightfully got the star billing, but in this case Silver Age is no haphazard add-on to the proceedings: it's the best album Mould has made since Sugar. Granted, standout tracks like "The Descent," "Fugue State," and "Keep Believing" are not quite all-time greats from Mould -- he's got a ridiculously consistent history of producing top-notch songs on every album he's ever done -- but the second tier of "Star Machine," "Silver Age," and "First Time Joy" are no slouches either; I've just named six of the ten tracks as excellent or better. As for the rest, there are no duds here: from front to back it's very good to great.
In short, it's the most focused and consistent work Mould has done since 1993, and his best album since 1995. It's great for longtime fans who've waited for the "next great Bob record" and for general rock fans who want something new to check out.
