Hattlerizer 3.0 is the latest incarnation of Max Hattler’s live audio-visual performance practice. Using custom-built software, Hattler expresses an abstract optical terrain in which hard-edged geometries and supple organic forms proliferate, interact, and wane. Aesthetics of geometric shapes and colours coalesce with optical feedback recursions to engross the audience with virtual realms that range from the soft, nebulous, and celestial, to the frenetic, psychedelic, and dissonant. Paying homage to influences in improvisational jazz and avant-garde animation, Hattler plays his visual instrument in an ad lib manner, resulting in a radiant spectacle that is at once arresting, rapturous, and starkly original. Spanish musician and sound artist VesperOn, Jordi Baldó, accompanies Hattlerizer 3.0 with an experimental electronic soundtrack composed and performed exclusively on a Nintendo Game Boy.
