In the spring of 2006, White, who was on break from Green Day, and Brooks, who had begun playing with the Canadian based band The Stills, began making trips back to Little Rock, to write a full length Big Cats album. This would become On Tomorrow, which was recorded with Barry Poynter at his studio in Little Rock. Pop Matters gave the record a rating of 6/10. Stewart Mason of All Music said about the album, "In some ways, the Big Cats are so retro they're positively cutting edge: this Little Rock quartet is a jangly guitar pop band from the South, a style of music that was absolutely everywhere in the post-R.E.M. '80s but has been decidedly absent from the cultural Zeitgeist for quite some time. On Tomorrow isn't some kind of archeological enterprise, however: this kind of low-key, earnest jangle pop is more timeless than that."
