Mike Einziger: Michael Aaron "Mike" Einziger (born June 21, 1976) is an American musician, best known as the guitarist and co-songwriter of the rock band Incubus.  Einziger is widely known as an innovator and enthusiast of the use of pedalboard guitar effects during live concerts, and was voted #41 in Total Guitar's top 100 guitarists of all time in 2002.  In an interview with Gibson Guitars, writer Steven Rosen states "[Einziger] hasn’t played the guitar so much as he has manipulated it, submitted it to his own needs.  Einziger fashions a sonic tapestry that draws heavily from the Zappa/Vai/Hendrix school of rock."  Mike is also an active composer, writing his first full-scale orchestral concert entitled "End.> vacuum", as well as "Forced Curvature of Reflective Surfaces"; an experimental composition that was featured at the "West Coast, Left Coast" Festival at Walt Disney Concert Hall.  He co-wrote and played acoustic guitar on Avicii's 2013 worldwide hit "Wake Me Up".  Alongside this, Einziger also recently co-wrote and played guitar on David Guetta's Lovers on the Sun.
