Time Signatures, hosted by Jim Ervin, features conversations with musicians, industry professionals, and others connected to the blues genre. Primarily focused on the blues, the program occasionally delves into other linked genres (ie. jazz, rock, soul, funk). Many of the episodes are recorded before a live audience at various venues in and around Mid-Michigan. The program is presented by the Lansing's Capital Area Blues Society, a non-profit blues organization dedicated to the promotion of, preservation of, and education about the blues. This is also the main goal of Time Signatures; acting as a digital time capsule, capturing moments in time, and providing a platform for future generations to hear the voices of those who have etched their own “signature” into the blues.
