Mainstream Records is a U.S. music label founded in 1964 by producer Bob Shad. At first, the label focused on reissuing historic recordings – such as those from Commodore Records and Time Records – while also building a strong profile in jazz. Renowned artists like Sarah Vaughan, Carmen McRae, Maynard Ferguson, Jim Hall, Zoot Sims, Clark Terry, and Helen Merrill released important works under its banner.

Beyond jazz, Mainstream Records also became known for launching groundbreaking rock debuts: the first albums by Janis Joplin with Big Brother and the Holding Company and by The Amboy Dukes featuring Ted Nugent were both released on the label.

In 1978, Mainstream Records ceased its original operations. During the 1990s, it was revived by Shad’s daughter Tamara together with Humphrey Walwyn. The label later passed to Legacy Recordings before being reacquired by the Shad family. Today, Bob Shad’s granddaughter Mia Apatow, supported by her brother Judd Apatow, continues to carry the legacy of Mainstream Records, keeping the name and its history alive.
