The musician born Josh Tillman chose the title for his sixth album in a decidedly Father John Misty kind of way: He found the Sanskrit word in a novel by Bruce Wagner, who shares with the musician a certain impish LA mysticism. Mahāśmaśāna translates to “great cremation ground,” so it’s no surprise to find the singer-songwriter in “what’s it all mean?” mode, trawling tragicomic corners of the American Southwest in search of answers about life, death, and humanity. After trying his hand at big-band jazz on 2022’s Chloë and the Next 20th Century, Tillman returns to the big, sweeping ’70s-style pop rock that’s earned him a place among his generation’s most intriguing songwriters. He channels Leonard Cohen’s Death of a Ladies’ Man on the sprawling title track, whose swooning orchestration and ambitious lyrics take stock of, well, everything. “She Cleans Up” tells a rollicking tale involving female aliens, high-dollar kimonos, and rabbits with guns, and on dystopian power ballad “Screamland,” he offers an all-American refrain: “Stay young/Get numb/Keep dreaming.”
