In some ways, Equal Strain on All Parts is what you’d expect from a new Jimmy Buffett album—more of what his fans have come to love (and his critics largely dismiss) over the past five decades. But knowing that this posthumous release represents his last set of new tunes, the album is dusted with a layer of sentimentality that brings a heightened, or at least more considered, appreciation of the famous/infamous singer-songwriter and entertainer. A few things make this record noteworthy, notwithstanding his recent passing: collaborations with Paul McCartney, Emmylou Harris, Angélique Kidjo and the Preservation Hall Jazz Band; two covers (“Mozambique,” a Bob Dylan classic, and “Like My Dog,” a country number popularized by Billy Currington); and a track called “My Gummie Just Kicked In” (‘nuff said). The latter likens the titular experience to riding a float in one’s own Mardi Gras, one of several musical and lyrical references to New Orleans, Jimmy’s temporary home before he settled in Key West. “Bubbles Up,” “Johnny’s Rhum” and “Nobody Works on Friday” fall into the island-inspired country genre that Buffett himself popularized, while “Audience of One,” is a mambo number a la David Byrne’s Rei Momo, and the music of “Fish Porn” explores a palette akin to Dawes’ Passwords album. With the title track, Buffett cites the wisdom of his elders (in this case, his grandfather’s description of a nap), as he’s been doing since “He Went to Paris,” the fourth single from 1973’s A White Sport Coat and a Pink Crustacean. Like that album, Equal Strain on All Parts will sound great on the beach or at a BBQ next summer.
