"A Matter of Trust" is a song by Billy Joel released as the second single from his album The Bridge.
The song was the second top 10 single from the album, after the previous single "Modern Woman." The song's music video features Joel and his band performing in the basement of a building on St. Mark's Place in New York City's East Village, and also features shots of various people in the city who eventually gather round the building's windows to see Joel perform. His then-wife Christie Brinkley appears in the video holding their baby daughter, Alexa. The song differs from most Joel songs in that is based on electric guitar rather than piano, his main instrument.
