On January 21 a variety of acts will take the stage in Chicago for an extended evening of bluegrass. The Auditorium Theater at Roosevelt University will host the night which will see full sets by the Del McCoury Band and David Grisman Quintet, followed by a special “Big Mon Jam” inspired by Bill Monroe, featuring Grisman with the Del McCoury Band. Del’s Boys will be busy because a second special set will be the Bluegrass Ball featuring The Travelin’ McCourys, a collaboration between that group and other artists yet to be announced. Also on the bill will be Joe Purdy, The Giving Tree Band and Majors Junction. The night is part of the extended Chicago Bluegrass and Blues Festival, with additional details here.
