PLB 0-06-027918-4 In a tongue-tangling word-romp, London (Hip Cat, 1993, etc.) invites children to “jump right in, to swirl and spin” with the animal-attendees of his sock hop. This swinging party features cool cats, whirling rabbits, frolicking dogs, cavorting mice, and springing frogs, all grooving in half-tugged socks. London combines the deeply satisfying sounds of drums and keyboards with the upbeat be-bop of the sax to create a book that, when read out loud (at story hours or anytime), rivals the cadence of rhythm and blues. Working in confident, vivid colors, Cole sets out a playful visual introduction to musical instruments; the scenes are fairly bursting with joyful dancers who are so engaging that joining the hip-hop hoppin’ may be the only way to go.
