Hetfield is mainly known for his intricate rhythm playing, but occasionally performs lead guitar duties and solos, both live and in the studio. Hetfield co-founded Metallica in October 1981 after answering an advertisement by drummer Lars Ulrich in the Los Angeles newspaper The Recycler. Metallica has won nine Grammy Awards and released ten studio albums, three live albums, four extended plays and 24 singles.
