Bob Goldstein is a Baltimore boy, whose office today is just a mile from the first house he lived in. His grandmother bought him a Fender bass and a Silvertone amp in the early 1960s, and he was quickly playing with local bands. He was at the local Hi-Fi store so much he got a job there, and by 16, he was sales manager. There he started working on P.A. speakers and amps.

Soon his talent as a sound engineer became well known and he went out the road with Frankie Valli, which was the start of relationship that continues to this day. He worked for the Clair Bros. for a short time before focusing on his own company. Through the years, he grew MSI nationally and internationally, and today in addition to supporting touring acts, they do installation, TV/Broadcasting, and even some highly specialized sensitive government work.
