Original Sound is a Los Angeles, California-based record label. It was founded in the early 1950s by KPOP deejay Art Laboe. It began as a small label that specialized in compiling and re-releasing "oldies" R&B and rock 'n' roll songs. The label pioneered the concept of reissuing older pop and rock hits, and sold millions of records on his Oldies But Goodies compilation albums, several of which made the national Billboard album charts. All 15 volumes of this series were later reissued on a best-selling CD series in the 1980s and 1990s, although track listings on each CD volume varied widely from the original LP issues with identical numbers, and some volumes contained none of the same songs as their original issues.
