The guitarist and occasional back up vocalist in canadian prog rock band Rush. His real name is Aleksandar Živojinović and is the son of Serbian immigrants. He is a highly talented guitarist, one of the best ever, but since no music media outlet ever cares about Rush, is often unappreciated. Plays a wide variety of guitars from Gibsons to PRSs. Can play better than just about anyone. He's nicknamed Lerxst from a mispronunciation of his name.
