Loose Monkeys collects rare songs, covers, and demos that showcase the questing nature of Graham Parker’s muse. His fine melodic sense and unromantic worldview are common factors across the flinty reggae of “Durban Poison,” the Beatle-esque pop of “Don’t Kid Yourself,” and the passionate soul of “Wherever You Are.” And needling acoustic demos like “Corporate Rock” and two contrasting versions of “I Just Can’t Capture Her Imagination” underline the singularity of his voice as writer and singer.
