Lars Ulrich ( /ˈʌlrɪk/ ul-rik; born December 26, 1963) is a Danish thrash metal drummer, and one of the founding members of the American thrash metal band Metallica. He was born in Gentofte, Denmark to an upper-middle class family. A tennis player in his youth, Ulrich moved to Los Angeles, California at age sixteen to pursue his training; though rather than playing tennis, he became a drummer. After publishing an advertisement in a local Los Angeles newspaper called The Recycler, Ulrich met James Hetfield and formed Metallica, and thus far, Ulrich and Hetfield have been the only members of the band to remain original members since the band's inception.
Ulrich became known as a pioneer of fast thrash drum beats featured on many of Metallica's earlier songs. He has since been considerably influential on heavy metal due to both the popularity of his band, as well as his drumming techniques.
