Albert The Ice Man Collins was an American blues singer and guitar player who was known for his use of a capo and alternate tuning on his guitar.
(He usually tuned the guitar to open Fminor (low to high: F-C-F-Ab-C-F), with a capo at the 5th, 6th or 7th fret.)

His guitar of choice was a Fender Telecaster and some call him the Master of the Telecaster.
Along with his band the Icebreakers, Collins  was known for his powerful and explosive playing of blues music.
