It's hard to say that 
Buddy Guy's career was revived by his appearance in 
the Rolling Stones' Shine a Light, but his mesmerizing duet on 
Muddy Waters' "Champagne and Reefer" in that Martin Scorsese concert film was a bracing, welcome reminder of just how good 
Guy is, especially for listeners who may have let their attention wander in the years since 
Damn Right, I've Got the Blues. What made 
Guy so riveting was his coiled aggression: in stark contrast to the deferential 
Jack White, he came to cut the 
Stones down and he did so mercilessly, which made it the musical highlight of a show with plenty of great moments. That wildness has kept 
Buddy Guy unpredictable well into his senior citizenship, and it surfaces on 
Skin Deep, only perhaps not quite as often as it should. Touted as his first album of original material, 
Skin Deep does work as an effective showcase for 
Buddy's most original voice: his wild, gnarly guitar. The production may be crisp and clean but 
Buddy refuses to play polite, messing up the pristine surfaces with big, nasty, ugly smears of guitar. Even when the record gleams too brightly -- as it does just a little bit too often -- 
Guy sounds like he's trying to tear things apart from the inside, which lends vigor and energy to numbers that are performed with just a shade too much preciseness. Thankfully, not all of 
Skin Deep is so clean, as the record opens up with a pair of dynamite collaborations with Robert Randolph -- the stripped-down, swampy Delta blues "Out in the Woods" and the muscular "That's My Home." 
Guy also gets in a couple of good numbers with 
Susan Tedeschi and Derek Trucks -- there's also a duet with 
Eric Clapton on "Every Time I Sing the Blues," which slides into a too-comfortable slow groove -- and these are the moments when 
Skin Deep really clicks, as the songs spark and the band truly cooks. Elsewhere, the music slips toward the conventional, but at least it sounds like 
Guy is trying to reel it back in with that monstrous guitar, which can still sound wondrous. It's kind of fun to hear the accidental tension between 
Guy's guitar and the slick surfaces, but when he's paired with a band or production that matches his grit, 
Skin Deep is so good that it's hard not to wish the whole record sounded just like that. ~ Stephen Thomas Erlewine
