Next week, the Tesla (TSLA.O) chief executive is set to square off in court against an unlikely foe - a thrash metal drummer who hopes to strip Musk of his $56 billion pay.Legal experts said such large shareholders are unlikely to sue because it might invite blowback from Musk and cut off access to management.Tornetta also turns up in videos drumming at the legendary former New York club CBGB with his now-defunct metal band "Dawn of Correction", which described its sound as "a swift kick to the face with a steel-toed work boot."10-FOLD RISE IN STOCK PRICETornetta's lawsuit alleges Musk dictated the pay package's terms to a board of directors beholden to the billionaire and claims it was then put to a vote of shareholders who were misled about the difficulty of reaching certain targets.Tornetta and his lawyers at Friedman Oster and Tejtel; Bernstein Litowitz Berger & Grossmann; and Andrews and Springer have stuck with the case for four years, hired experts and conducted more than a dozen depositions."
