The general plan is for the entire ensemble to gradually converge in unison on the "head" melody as written inside the horizontal lines. Once convergence has been achieved, the unison line should be played a minimum of 3 times before the final, conducted cutoff which ends the piece.
Each player should make several passes through the score before playing the head. Play cells from left to right. Repeat each cell as many times as desired. Transformations and distortions of all kinds (diminution, augmentation, transposition, inversion, retrograde, timbral manipulation, etc.) are allowed while playing cells outside the head. Rest between cells outside the "head" as long as desired. Start from the outsides of the page (jumping randomly between upper and lower frames) and gradually work your way toward the middle with each successive pass through the score. The question mark cells are freely improvised. All percussion and doublebass parts are to be freely improvised, but should try to sync up with the unison line once it "coalesces". The overall dynamic and density should increase from pp to ff at the point of coalescence, then remain ff until the end.
