Early life

Dave Mustaine was born in La Mesa, California, to Emily (née David) and John Mustaine. Dave's parents are of French descent and his mother has Jewish ancestry. He was brought up as a Jehovah's Witness. Dave has also described his heritage as 'I am not a Jew, I'm a Christian of Jewish descent'. In an interview with Spin magazine, Dave said that one of his most prized possessions is a giant shofar his Mom gave to him as a present. By the age of 17, Mustaine had rented his own apartment and was surviving financially by dealing drugs. One of his clients, Willow[citation needed], was often short of cash, but worked in a record store, so in return for drugs, she offered albums by artists such as AC/DC, Motörhead and Judas Priest in trade, which helped form his taste in heavy metal. In the 1970s, Mustaine began playing piano and later electric guitar, most notably a B.C. Rich and joined a band known as Panic for a short time.
