It has always been a nonstop party with the Donnas. And we aren’t complaining. The group’s brand of straight-ahead, no-frills rock’n’roll has consistently been gobs of fun and refreshing to hear, especially in the age of Pro Tools-primed pop music. On their last album, “Spend the Night,” the four Donnas couldn’t get enough of sex, boys and booze. With “Gold Medal,” the ladies may have aged a bit, but they haven’t exactly changed their game plan. Which is very fine, especially when it results in such potency as “It’s So Hard.” Here, a cocky chorus leaves little to the imagination: “It’s so hard to be on your own/When you’re holding it all alone/And you’ve been working it to the bone.” Of course, that’s the great thing about the Donnas. They churn out seriously fun, ballsy rock tunes with a wink and a nod. Do not ignore the tracks “I Don’t Want to Know” and lead single “Fall Behind Me.”—KC
