Infrequent Twitter user Adele took to her account this morning to post a lengthy, personal letter detailing her long-awaited new album 25. The missive is coming on the heels of a mysterious snippet of new music debuted during a commercial break in the UK this weekend, a clip that counted as her first piece of new material since her 2012 Bond theme "Skyfall." "My last record was a break-up record and if I had to label this one I would call it a make-up record," writes the singer. "I'm making up with myself. Making up for lost time. Making up for everything I ever did and never did."

The release of a new Adele record is the kind of momentous occasion that has the power to impact the entire music industry. Her last album, 2011's 21, sold over 30 million copies worldwide, and it generated three straight #1 singles in the US — unless you've spent the last half-decade in a Fallout vault and have only emerged in recent weeks, you know the words to "Rolling in the Deep" and "Someone Like You," consciously or not. There's still no single, release date, or tracklist in sight for 25, but we know a little bit about the producers and writers who helped to make it. Danger Mouse, Max Martin, Tobias Jesso Jr., and Ryan Tedder were all involved in the recording process, and they could all contribute one or more tracks to the final product.
