A mask is all it takes to give a sleepy monster a voice. Fill seven spots with beats, grooves, melodies and vocals, then listen to the band you have made. Swap a mask, leave a little space or solo one performer: there is no score to chase and no wrong ending.
Choose a mask, find a sound, and see who joins in.

Layer beats, grooves, melodies and voices across seven monster slots. Mute or solo a part to hear how it fits.
Day and night each have twenty masks. New parts join on a musical boundary, keeping the eight-second loops together at 120 BPM.
Each mode has four secret combinations. Find one to add its 16-second performance to your bonus wall.
