Jamiroquai's sophomore record had all the slinky grooves and great musicianship of the debut, but it also offered a better set of songs and more ambitious musical themes. As with Emergency on Planet Earth, Jason Kay's dead-on impression of Stevie Wonder and Sly Stone drives the group's blend of acid jazz and funky R&B. "Space Cowboy" and "Light Years" were hits all over the world, and made the band stars in Europe and Japan, while substantial clubplay earned them a degree of recognition for American audiences. But Jamiroquai refused to be known as simply a party band; the group takes on social issues such as homelessness and Native Americans' rights.
