Back to the Grindstone is the twenty-first studio album, produced by Ronnie and Rob Galbraith (with further assistance from Richard Landis on “Since I Don’t Have You”), and released on March 12, 1991. The album produced four singles, three of which reached the top ten on the Billboard country singles chart, including “Are You Lovin’ Me Like I’m Lovin’ You,” “Since I Don’t Have You,” a cover of The Skyliners’ 1958 standard and “Turn That Radio On.” The fourth single, “All Is Fair in Love and War” peaked at number 11.
The album reached number 24 on country charts, and was Milsap’s last crossover until Then Sings My Soul in 2009, peaking at number 172 on the Billboard 200. Allmusic praised Milsap for a “gutsy [and] powerful performance” on the record, stating that “not one of the ten songs…is weak.” The publication characterized it as “one of his best albums,” lauding the performer’s “eclectic, soul-inflected R&B” style.
