Scott Spencer Storch (born December 16, 1973) is an American record producer and songwriter. Storch began his career as part of Philadelphia-based hip hop band the Roots, which he joined as a keyboardist prior to the release of their 1993 debut album, Organix. He provided the keyboard riff and co-composed Dr. Dre's 1999 single "Still D.R.E.," and contributed in a similar role to several of the rapper's productions during late 1990s and early 2000s. Storch expanded his solo production work into the 2000s; he was credited on five Billboard Hot 100-number one singles—Beyoncé's "Baby Boy," Terror Squad's "Lean Back," 50 Cent's "Candy Shop," Mario's "Let Me Love You" and Chris Brown's "Run It!"—among other similarly successful chart entries throughout the remaining decade. Storch has been nominated for four Grammy Awards.
