Zakk Wylde (born Jeffery Phillip Wiedlandt on January 14, 1967 in Bayonne, New Jersey) is the lead guitarist, best known for his role as singer and songwriter of Black Label Society and guitarist for Ozzy Osbourne. Wylde was the lead vocalist and guitarist in "Pride & Glory", who released one self-titled album in 1994 before disbanding. He has also released solo album entitled "Book of Shadows" that contained a much different style of music than he had produced in the past, with a focus on acoustic guitar playing.

Zakk Wylde's guitar-playing style is characterized by his use of pinch harmonics and wide/aggresive vibrato. His guitar soloing technique is usually characterized by use of the minor pentatonic scale, playing rapid box-pattern licks using strict alternate-picking, creating a very distinctive, choppy style of playing. Another notable feature of Wylde's playing is his liberal use of "chicken pickin' ," a technique which is usually associated with country music, and which is (comparatively) rarely seen in heavy metal; a technique he has stated as being picked up from watching Albert Lee.

On January 17, 2006, Zakk Wylde was immortalized at the Hollywood Rock Walk of Fame located at 7425 Sunset Blvd, featuring his hand prints and signature, in recognition to his successful career as a musician and contribution to music industry.
