The Youngbloods' sophomore release Earth Music is an uncommonly solid follow-up, expanding upon the musical directions introduced on their debut LP. The infectious "Sugar Babe" (also featured in Michelangelo Antonioni's film Zabriskie Point) is one of the group's most popular tunes, while such numbers as "All My Dreams Blue," "Dreamer's Dream" and "Fool Me" demonstrate the strength of the band members' songwriting skills and customized covers of Tim Hardin's "Reason to Believe," the Holy Modal Rounders' "Euphoria" and Chuck Berry's "Monkey Business" demonstrate the Youngbloods' talent for seamlessly integrating a broad array of influences.
