You know it. With the lights out, it's less dangerous. These lullaby renditions of Nirvana's best-loved songs turn the volume way down while turning up the dreaminess of their pop hooks. In many ways, this album echoes the simple pleasures and innocence of infancy and childhood. Childish tra-la-la's tempered with the distortion of Nirvana's own songs. Chimes, glockenspiels and other instruments temper Nirvana's wild spirit for your little one. "Smells Like Teen Spirit?" Smells like nap time.
