Sincerely is the debut album from the Dwight Twilley Band, released in 1976 on Shelter Records. The band consisted solely of Dwight Twilley (guitar, piano, lead and harmony vocals) and Phil Seymour (drums, bass, percussion, lead and harmony vocals), although touring band member Bill Pitcock IV played lead guitar on every song except for "Sincerely" itself. The album credited production to Oister, which was the original name of the Dwight Twilley Band; later reissues have credited production directly to Twilley and Seymour.
