Jay Bradley Weinberg (born September 8, 1990) is an American musician who is best known as the former drummer of the heavy metal band Slipknot.

[11][14] He joined the New York punk band the Reveling in August 2008, which plays before small audiences in venues such as the Ace of Clubs nightspot in Manhattan, various spots in Brooklyn, and elsewhere.

[12] Jay Weinberg's first appearance with Springsteen was in the summer of 2008, filling in for his father on "Born to Run" at Giants Stadium after having watched many other performances during the Magic Tour.

[16] Springsteen's manager Jon Landau viewed Weinberg as the "secret weapon" to substitute for his father without losing fan satisfaction.

[3] Both Landau and E Street guitarist Steve Van Zandt attributed Jay Weinberg's skills to a genetic gift.

[11][15][18][19] He received a very positive reaction from both audiences and reviewers as a re-energizing "spark plug"[19] for the much-older band,[20] with his vigorous, long-hair-flying style inviting comparisons to Dave Grohl[21] and his potential for replacing his father drawing allusions to Wally Pipp.

[12][20] Modern Drummer magazine's editor said that a college freshman playing on one of the year's biggest rock tours is "certainly a unique story".

[12] Weinberg played a number of dates early on in the European second leg of the tour, including at the Dutch Pinkpop festival in Landgraaf, Netherlands in addition to Bonnaroo in Manchester, Tennessee.

"[15] On June 22, 2024, Weinberg made a surprise appearance on drums for the song "Radio Nowhere" at Springsteen and the E Street Band's show in Barcelona, Spain during their 2023-2024 tour.

[22] However, in September 2010 the group discharged him, with Madball vocalist Freddy Cricien saying, "I'm letting Jay go [mid-tour] in Canada because I just feel he doesn't represent this band well on a character level.

for their upcoming 2011 shows, covering for regular drummer George Rebelo while he toured with his other band, Hot Water Music.

Weinberg was recruited by Infectious Grooves for the band's first live appearances since a one-off show in 2019 due to Wackerman's commitments to Avenged Sevenfold.

[36] Jay Weinberg currently endorses SJC Custom Drums, Zildjian Cymbals, Evans Drumheads, DW Hardware, Roland, and Vater drumsticks.
