This week's Theater Loop Showcase video is a song from Cheryl L. West's "Pullman Porter Blues," currently onstage at the Goodman Theatre. Set in 1937 on the Panama Limited Pullman Train from Chicago's Union Station to New Orleans, the show depicts three generations of African-American porters, each representing monumental social changes. One passenger aboard is Sister Juba, a likable lush of a blues singer played with zest by E. Faye Butler. West's play is punctuated by character-informed blues songs like this one, "Trouble in Mind," performed here by Butler. "Pullman Porter Blues" plays the Goodman Theatre through Oct. 27; Chris Jones has the review.

We filmed this video, a song from the show, at our studio in Tribune Tower.
