Eric Clapton's Unplugged was responsible for making acoustic-based music, and Unplugged albums in particular, a hot trend in the early '90s. Clapton's concert was not only one of the finest Unplugged episodes, but also some of the finest music he had recorded in years. The music was straightforward and direct, alternating between his pop numbers and traditional blues songs. The result was some of the most genuine, heartfelt music the guitarist has ever committed to tape. And some of his most popular - the album sold over seven million copies in the U.S. Unplugged won the 1993 Grammy Awards for Album of the Year, Best Male Pop Vocal Performance and Best Male Rock Vocal Performance. "Tears In Heaven" won the Grammy for Song of the Year and "Layla" was named Best Rock Song.
