1) Classic rock mainstays, Chicago and the Doobie Brothers, who both racked up numerous hits during the 70’s, are joining forces tonight at First Niagara Pavilion. Chicago’s brassy horn section gives extra depth to hits like 25 or 6 to 4; Saturday in the Park; Just You and Me; Beginnings; If You Leave Me Now. Chicago had a longer name at their start. They called themselves the Chicago Transit Authority, but were forced to change it. The Doobie Brothers, California rockers, will dip into their rich catalog and play songs such as China Grove; Takin’ It to the Streets; Blackwater. 8 p.m. Burgettstown.
2) They say “eat your greens” for a better life. Well, today you can “eat your blues.” Nancy McKeen Bluz Machine is playing an unplugged concert in Mellon Square Park during the lunch hour.
