Canadian pop-punk superstars Sum 41 have entered the studio to begin work on their next full length, and first without founding guitarist Dave Baksh who left the band in May.

The band explained the rigid production schedule that major labels require them to adhere to:

Here's a recap of day one: we arrived at the studio, set up the drums, looked at them for a while, hit them, moved them, and then moved them again. Then, we sent the runner to get some booze and got moderately to extremely drunk. Very professional indeed!

We have three tracks to do today. Or at least, there are three tracks we'd like to do. Finding time to get them done between our daily regimen of breakfast, luch, drinks, beers, aperitifs, off-track gambling, nostalgic storytime, naptime, playtime and bedtime, will be a feat unto itself.

The band released Chuck in 2004.
