From his wiki:
Brian Harold May, CBE (born 19 July 1947) is an English musician and astrophysicist most widely known as the guitarist, songwriter and occasional singer of the rock band Queen. As a guitarist he uses his home-built guitar, "Red Special", and has composed hits such as "Tie Your Mother Down", "I Want It All", "We Will Rock You", "Fat Bottomed Girls" and "Who Wants to Live Forever".
He was made Commander of the Order of the British Empire in 2005 for "services to the music industry and his charity work". May earned a PhD in astrophysics from Imperial College in 2007 and is the 4th and current Chancellor of Liverpool John Moores University. May currently resides in Surrey.
In 2005, a Planet Rock poll saw May voted the 7th greatest guitarist of all time. He was ranked at No. 26 on Rolling Stone magazine's list of the "100 Greatest Guitarists of All Time".
I knew he built the guitar with his dad, and that its body had some hollowing to give it its characteristic sound.
