A dark ritual with unstable motion defines this concert band work whose title explains its character. "War" reflects the driving intensity associated with Holst's Mars; "Seven" points to the persistent 4/4 + 3/4 mixed meter, and "Serpents" draws on the snake‑ritual imagery of Revueltas' Sensemaya. Triplets, accidentals, a variety of solos, and shifting meters feel bold yet approachable for young players. A compelling choice when young bands are ready to sound sophisticated while developing rhythmic confidence and deep ensemble focus.
