Alex Alvarez is best known as Lenny Kravitz' guitar tech but after 25 years, he is in many ways Kravitz' right-hand man. For tours, he's the crew chief, responsible for hiring the crew, maintaining the equipment, and much more. Off tour, he manages Kravitz' studios in Paris and the Bahamas. Wherever Kravitz and his band go, you'll find a Mackie mixer in use.
