Chicago blues guitarist John Primer and Arizona (by way of Chicago) harp master Bob Corritore team up for the first time on this session of raw Chicago blues, Knockin' Around These Blues. It's odd these two have never collaborated on a project, as Primer began playing the blues in the early '70s at the famous Chicago club Theresa's, while, at the same time, Corritore started hanging around the Windy City learning the harp from such legends as Walter Horton, Carey Bell, and Junior Wells. The ten-track program boasts gutsy, heartfelt cover versions of material by Little Walter ("Blue and Lonesome"), Robert Lockwood Jr. ("Little Boy Blue"), Willie Dixon ("Just Like I Treat You"), Jimmy Reed ("The Clock"), and Lightnin' Hopkins ("Going Back Home"). Rounding out the band are guitarists Billy Flynn and Chris James, pianist Barrelhouse Chuck, bassists Bob Stroger and Patrick Rynn, and Kenny "Beedy Eyes" Smith and Brian Fahey on drums.
