Weinberg is the son of drummer Max Weinberg, who joined the E Street Band in 1975; his mother, Rebecca "Becky" (Schick), was a former teacher. He grew up in Middletown Township, New Jersey. His mother was a Methodist and his father Jewish. His sister is Ali Weinberg Rogin (married to Josh Rogin). As a child, he played travel team ice hockey as a goaltender. At age 9 he first saw the E Street Band on their 1999–2000 Reunion Tour, and saw shows on this and subsequent tours, especially in Europe. Around the same time his father took him to Ozzfest to see Slipknot, which gave him a strong affinity for heavy metal and other intense music genres; his father also exposed him to a wide variety of other music. He began playing guitar at age 9, bass at age 12 or 13. He then started playing drums at age 14, getting only few lessons from his father without much instruction and being mostly self-taught, using his father's old gear. By the next year he had performed a guest appearance on stage with band The Used and subsequently with punk rockers the Bouncing Souls. He played in the New Jersey metal band Chaosis. He attended Rumson-Fair Haven Regional High School where he played on the hockey team for a time, played in a band called Sadie Mae, and graduated in 2008.
