On their playful, rock-driven fifth studio album, The Waifs take a cue from former tour partner Bob Dylan, going electric with wild abandon. After joining the legendary troubadour on the road in 2003 to support their acclaimed folk-pop collection Up All Night, the beloved Western Australian folk trio let loose on 2007’s rollicking Sun Dirt Water. Guitarist Joshua Cunningham takes on most of the songwriting, injecting the band’s rustic melodies with raucous riffs and bluesy licks via harmonica-soaked anthems (“How Many Miles”), organ-rich stompers (“Stay”) and feel-good country jams (“Eternity”). Meanwhile, sisters Vikki Thorn and Donna Simpson prove they’re natural rockers, lending a heavy dose of soul and seduction—especially on Simpson’s devilish bar-room romper “Sad Sailor Song” and Thorn’s jazzy title track, an earthy ode to everlasting love. Recorded in Nashville, the album gets a boost from notable Music City session musicians. Keys master Reese Wynans bangs hardest on the gospel-touched torch song “Sweetest Dream”, while Jeff Coffin slips in some mood-setting clarinet on the old-timey ukulele lullaby “Feeling Sentimental”, a winking, unplugged ode to nostalgia.
