John Prine's second album was a cut below his first, only because the debut was a classic and the followup was merely terrific. "Sour Grapes" showed Prine's cracked sense of humor and "Souvenirs" his sentiment. Even if it was the second rank of his writing, Diamonds in the Rough demonstrated that Prine had an enduring talent that wasn't exhausted by one great album. ~ William Ruhlmann
