Another fabulous story from the author of Bats at the Library and Bats at the Beach, this one follows the bats as they wake from winter’s hibernation anxious to make a little noise.  Finding a window open at a deserted summer theater, the bats indulge in an evening of music-making.  Told in rhyming verse, with illustrations depicting some bats with actual miniature instruments while others play on improvised hand-made instruments, the story winds its way through the bats’ concert, describing an assortment of different types of instruments and different types of music along the way.  It celebrates music of all kinds.
