Milwaukee, Wisconsin: An Internal medicine specialist also plays in a rock band. It’s Jewish. Also was a bass player for Shlock Rock,… “the most prolific Jewish rock band in history. 14 albums and counting….” . Now he works on his own and is doing more writing. Musical examples, bio and info on newest CDs, such as Rock of Sages on the website. Mark and others in the bands he’s played in, have been a big influence in Jewish-themed rock music.
