"We sparked a new kind of life into what we do during the writing of ('Midnight')," Bennington told Billboard.com. "We want to keep that going. I think we're in the mode, and I have a good feeling we're going to put another record out really quickly."
"There was a long period of time between the release of 2003's 'Meteora' and 'Minutes to Midnight'," Bennington said. "Even though we did tour (for 'Meteora') for two years, we didn't start working on writing ('Midnight') until seven months after we stopped touring. So it seemed like a really, really long time to our fans and it seemed like a really, really long time to us. I don't see that happening again."
yeah I hate the fact I have to wait 3 or 4years for new lp albums but I'd rather them take 3years and make a awsome album that the band love then taken 1year for a crap album that the band hate
