Alejandro Escovedo plays a free show Friday at Grant Park’s Petrillo Music Shell. Escovedo’s near death from Hepatitis C has infused his music with depth and introspection without weakening his ability to rock. In June, he released Real Animal, produced by Tony Visconti of T. Rex and David Bowie fame. Escovedo opens for Old 97s and Gomez; show starts at 3 PM. Click here or call 312-744-3315 for more info.
