Jordi Herold and John Riley opened the club on February 24, 1979, as a bohemian cafe with 85 seats. The club (doubled in size in the late 1980s) is home to many kinds of music and talent ranging from popular local performers to artists of international repute. In college, Herold fantasized about opening a club and placed a bid on space in Amherst.[verification needed] After limited initial success, he began teaching for the Amherst, Massachusetts public school system.
John Riley was responsible for bringing the first jazz shows into the club. In the early years of operation, music was really a complement to the room's ambiance as opposed to the main event, live music was limited to a strict format of classical chamber music (Thursdays), jazz (Fridays), and folk and classical (Saturdays), and the talent was mostly local. The club gained recognition when national acts Dave Van Ronk and the Heath Brothers played the club during its first year.
The venue was shuttered in March 2020 at the start of the COVID pandemic and as of early 2023.[3]
At its February 14, 2023 meeting, the Northampton License Commission told Eric Suher, the owner The Iron Horse Music Hall, that it will cancel the liquor license for the venue if is not reopened by June 1.[4]
In September 2023, The Parlor Room, Inc., the non-profit operator of the Parlor Room music venue, announced that they had signed an agreement to acquire The Iron Horse and reopen it.[5] After a significant renovation the venue reopened on May 15, 2024.[6]
