Journalist Nik Cohn described him as "rock's greatest ever natural talent". Prince was a natural tenor, but had a wide vocal range from falsetto to baritone, and performed rapid, seemingly effortless shifts of register. Prince was also renowned as a multi-instrumentalist. He is considered a guitar virtuoso and a master of drums, percussion, bass, keyboards, and synthesizer. On his first five albums, he played nearly all the instruments, including 27 instruments on his debut album, among them various types of bass, keyboards and synthesizers. Prince was also quick to embrace technology in his music, making pioneering use of drum machines like the Linn LM-1 on his early '80s albums and employing a wide range of studio effects. The "LA Times" also noted his "harnessing new-generation synthesizer sounds in service of the groove," laying the foundations for post-'70s funk music. Prince was also known for his prolific and virtuosic tendencies, which resulted in him recording large amounts of unreleased material.
