Popular music returns to the hill in Jacksonville tonight, when rock legends Chicago play in a sold-out concert.

A Medford musician, Eric von Radics, opens the 7:30 p.m. show.

Chicago may be best known for tunes of the 70s, but the band has produced 29 albums in all and has toured continually since forming in the late 60s.

It played in two shows last summer and sold out the venue again this year.
