Kerplunk, released in 1990, was Green Day's last album on the Lookout Records label.
By 2002, Lookout began to shift focus from its East Bay pop punk roots to a more diverse sound by releasing albums from bands such as Pretty Girls Make Graves, Ted Leo And The Pharmacists, The Oranges Band and Neuman's own band Bratmobile
  Green Day realized that they had outgrown their record distribution capacity with Lookout! and eventually signed with Reprise Records
