Nierow began playing piano as child, learning the instrument quite rapidly; by the age of 11, he was playing Haydn concertos. However, he was restless and quickly grew tired of classical music, becoming infatuated with jazz as a teenager. In fact, after Nierow finished studying music at Brooklyn College, he became a jazz pianist. However, instead of playing straight jazz, he created a swinging hybrid of jazz and classical music.
Nierow didn't have much success as a performer, which meant he had to take a gig as a saloon pianist in a New York club called the Hickory House. Unsatisfied with the comprimises he was making at the club, he headed out to Las Vegas, where he didn't find much success. He returned to New York, taking a lesser job at the Hickory House. For several years, he played New York's club circuit before he came to the attention of Stan Greeson, an executive at RCA Records. Convinced that Nierow had star potential, Greeson signed the pianist and had him change his name to Peter Nero; he also persuaded Nero to add pop songs like "Over the Rainbow" to his repertoire.
Piano Forte, Peter Nero's first album, was released in 1961 and he began touring the country. That same year, he won the Grammy for Best New Artist. Nero's popularity continued to rise throughout the early '60s; his jazzy hybrid of pop, classical, swing, and bop became one of the most popular mainstream sounds of the era. Eventually, he became the musical director of the Philadelphia Pops Orchestra, where he frequently performed classical arrangements of pop songs. In the '70s, he returned to playing jazz in trios, though he still made orchestral records occasionally. ~ Cub Koda, Rovi
