Solid Gold: 30 Golden Hits, also called 30 Golden Hits/21 Golden Years, is a greatest hitscompilation album by James Brown. The double album set was initially released in 1977 on Polydor, and was re-released by the label in 1986. The album's liner notes listed the release dates and U.S. chart positions for each song and included an essay by Cliff White. This is the first compilation album to include Get Up(I Feel Like Being a) Sex Machine. According to Allmusic reviewer William Ruhlman, the collection was "state-of-the-art", an influential model "not only...for the many Brown compilations that would follow in later years, but also for the compilation boom in general". In 1981, Village Voice critic Robert Christgau described it as "an essential collection." Allmusic indicates that it supplies "the essence of James Brown", but also states "[i]t has since been superseded by the 1991 four-disc Star Time boxed set".
