For years, Chicagoans could hear world-class musician Jon Weber just by stepping into the lounge at Chicago’s Four Seasons Hotel. Now, people all over the country will be able to hear Weber as he steps into Marion McPartland’s roll as host of the syndicated radio program Piano Jazz. Actually, the show--and its name, is being tweaked just a bit. Weber recently sat down with WBEZ’s Richard Steele to talk about his musical journey, which he said began as a kid in Milwaukee.
