Not to be confused with the action/political thriller 'Decker', Dekkar is a progressive and hard rock band fronted by Tim Heidecker. The other band members are Axiom, Manuel, Vinny, and Nick. Since season 7, Tim has been using On Cinema and Decker to promote his group, often at the expense of discussing movies. This leaves Gregg annoyed whenever they make an appearance. Axiom and Manuel have sometimes appeared as guest stars in both On Cinema and Decker. Their signature hits include "Empty Bottle" and "Trigger Everything".
