A snazzy, colorful picture book that celebrates the many different kinds of music found within a city. A little girl whose favorite music comes from the streets does not like the concert hall, where the orchestra ""just plays and plays,"" even though her grandmother says it is a treat to hear the symphony. She prefers to ""rapa-tapa-tapa on the hot concrete,"" where the maid with her Dixieland mop is ""soppin' with the boppin' all around the bus stop."" The next time Grandma says they are going to the symphony, the little girl refuses. . .until she learns that the orchestra will play in the park after dark. As in Annie Bananie, Komaiko has penetrated the facade of childhood; her rhythmic, be-bopping text reflects the uninhibited tempo of the street music preferred by the heroine. Westman's bright, energetic illustrations celebrate the vibrancy of city life.
