Reception
The album was awarded 4 stars in an Allmusic review by Stephen Thomas Erlewine who states "As he delved deeper into commercial soul-jazz and jazz-funk, Lou Donaldson became better at it. While lacking the bite of his hard bop improvisations or the hard-swinging funk of Alligator Bogaloo, Midnight Creeper succeeds where its predecessor, Mr. Shing-A-Ling failed: it offers a thoroughly enjoyable set of grooving, funky soul-jazz... Donaldson could frequently sound stilted on his commercial soul-jazz dates, but that's not the case with Midnight Creeper. He rarely was quite as loose on his late-'60s/early-'70s records as he is here, and that's what makes Midnight Creeper a keeper".
