Compound Interest. Compound interest is calculated each period on the original principal and all interest accumulated during past periods. Although the interest may be stated as a yearly rate, the compounding periods can be yearly, semiannually, quarterly, or even continuously.
The band was formed in 1981 when vocalist/guitarist James Hetfield responded to an advertisement posted by drummer Lars Ulrich in a local newspaper. Metallica's current line-up comprises founding members Hetfield and Ulrich, longtime lead guitarist Kirk Hammett and bassist Robert Trujillo. Guitarist Dave Mustaine and bassists Ron McGovney, Cliff Burton and Jason Newsted are former members of the band.
Trujillo's predecessor in Metallica, Jason Newsted, was almost exclusively a pick-style player, while Cliff Burton, Newsted's predecessor and bassist on Metallica's first three albums, played finger-style exclusively. Trujillo is known for playing massive chords and chord-based harmonics on the bass.
