Since his earliest days, John Hiatt has maintained a restless sense of adventurousness in his music, and even his long-awaited commercial breakthrough in the late ‘80s never kept him from trying on new sounds. The title track from his 1974 debut album Hangin' Around the Observatory is a winningly quirky country ditty about stargazing, while 1990's “The Rest of the Dream” is a Supertramp-worthy slice of piano-driven power pop.
