99 (also spelled pageninetynine) was a hardcore punk band from Sterling, Virginia, a town on the outskirts of Washington, D.C., who are widely considered one of the pioneers of the screamo genre.

The band formed as a six-piece in late 1997 and broke up as an eight-piece in 2003; at their maximum capacity they performed with two singers, four guitarists, two bassists and a drummer and were known for their intense live shows.

Before officially breaking up, Pg.99 booked Steve Albini of Shellac and Big Black as their producer for a follow-up to Document No. 8.

[4] Two releases completed before the group's break up have yet to see light: a DVD compiling various live footage, and a split 10-inch with City of Caterpillar containing both bands' last songs recorded.

"[5] After the Best Friend's Day festival sold out, Pg.99 scheduled a second performance on August 27, 2011, at The Black Cat in Washington, DC.

[8][9] In a group interview with NPR, Pg.99 was asked about the possibility of recording new material, and several of the members gave conflicting responses.

[10] Mike Taylor has mentioned plans to release a "long hidden" Document #15 through his Yr Screaming Youth imprint sometime in the future.

[11] On August 6, 2023, pageninetynine performed at New Friends Fest as the closing act of the three day music festival in Toronto, Ontario.
