He is the founder, main songwriter, primary guitarist, keyboardist and only remaining original member of the rock band Boston.

A fan of rock music throughout his teen years, Scholz began writing songs while earning his master's degree at MIT.

[3] He was described by AllMusic as an "un-rock n' roll" figure who did not enjoy the limelight of being a performer, preferring to concentrate on music, production, and inventing new electronic equipment.

Most of the guitar, bass, and keyboards were performed by Scholz, although other players were involved sporadically throughout the recordings, most notably drummer Jim Masdea.

While the album was being completed, Scholz and Delp added three additional local musicians to round out the band, who played little if anything on the record itself: bassist Fran Sheehan, guitarist Barry Goudreau and drummer Sib Hashian.

[15][16] After Brad Delp's suicide in March 2007, his adult children organized a concert in his memory on August 19, 2007, at the Bank of America Pavilion in Boston and invited the group to perform.

[17] Fran Cosmo was unable to sing because of a vocal injury, so Scholz invited guest singers to appear in his place, including Michael Sweet from Stryper and long time Boston fan Tommy DeCarlo who, after auditioning for Scholz, made a guest appearance on lead vocals.

Early Boston members Barry Goudreau and Fran Sheehan also appeared, joining Scholz on stage for the first time in over 25 years.

[20] In 1987, he established a charitable foundation, the DTS Charitable Foundation,[21] which has a variety of missions: supporting animal protection, providing vegetarian resources, stopping world hunger, creating homeless shelters, food banks, animal rescues and sanctuaries, and advocating for children's rights.
