Based on a pun of the situation in baseball where all the bases have runners on them and the player at bat has the intense potential to hit a home run and score four runs (termed a "Grand Slam"), this work is a funky feature for the "basses" of the band. The work was written for the tuba/euphonium quartet, Sotto Voce, and is intended as a piece for a quartet or tuba ensemble to close out a concert. It features an improvisation section so the players can create their own solos over the funky bassline.
