Bradford Phillip Delson (born December 1, 1977) is an American musician, best known as the lead guitarist and one of the founding members of the Grammy Award winning rock band Linkin Park. He is also the A&R Representative for Machine Shop Recordings.
Brad Delson attended Agoura High School with childhood friend and Linkin Park band mate Mike Shinoda. He played in various bands throughout his high school career, the most notable being Relative Degree, in which he met and teamed up with drummer Rob Bourdon. Relative Degree's goal was simply to play a show, and, after achieving that goal, they disbanded.

After graduating in 1995, Delson, Shinoda, and Bourdon formed Xero, which would eventually become the starting point for Linkin Park.

Delson entered UCLA in 1995 as a Regent Scholar working toward a Bachelor of Arts degree in Communication Studies with a specialization in Business and Administration. He was a member of Phi Beta Kappa, and shared a dorm room with future Linkin Park band mate Dave Farrell for three out of his four years at school. Delson also had the opportunity to intern with a member of the music industry as part of his studies and ended up working for Jeff Blue, an A&R representative at Warner Bros. Records, who offered constructive criticism on Xero's demos. Incidentally, it was Blue who later introduced Chester Bennington, the current lead vocalist of Linkin Park, to the rest of the band.

After graduating summa cum laude in 1999, Delson decided to forgo law school in order to pursue a musical career with Linkin Park. He remains an avid fan of all things blue and gold.
