When your life is consumed with making and performing music, you need to be able to retreat into something non-musical so your creative energies can recharge. Some musicians paint (Bowie, Iggy), make sculptures (Dylan), race cars (Brian Johnson), magic (David Lovering of the Pixies) or cook (Action Bronson), all things far more healthy than, say, developing a heroin habit.
