I had the honor of playing many shows with Mark over the years. One of which was the Surf Ballroom in Clear Lake Iowa. He was a gifted musician,who was able to play many intruments well. Whenever a local band was in a spot and needed a sub, Mark got the call. All the bands knew and respected his talent. The live music scene in Chicago has lost a true musician and friend. My heartfelf thoughts and prayers go out to Mark's wife Flo and the Eskin family. Rest in Peace Mark ~ Tony Bicek
