In an ironic intersection of two systems — arcane theoretical discourse and popular music — Baldessari sings a tract by Minimalist artist Sol LeWitt. Introducing this performance by noting that "these sentences have been hidden too long in exhibition catalogues," Baldessari sings Lewitt's forty-five-point tract on Conceptual Art to the tunes of The Star-Spangled Banner and Heaven, among other songs. Baldessari's witty "art aria" functions as a meta-conceptual exercise.
