Homestuck Vol. 9 is the twentieth official album released on the Homestuck Bandcamp, and the ninth installment in the Homestuck Volumes series. Encompassing all of Homestuck Act 6 as told until the release of the album, Vol. 9's primary focuses are the four alpha kids from B2 Earth and the twelve alpha trolls from Beforus, and the events of which they are a part.
Continuing the lofty tradition of the previous Homestuck Volumes, Vol. 9 is a truly impressive 51-track album that breaks away from the darker tone of its previous two predecessors and spans a wide variety of moods as well as genres and instrumental styles. Each individual track parallels music previously released in the Homestuck discography, just as Act 6 parallels Acts 1-5 of Homestuck and the newly introduced universes parallel their counterparts.
- The second bonus track, "Frustracean", contains a several minute long stretch of silence, at the end of which is a distorted voice clip of Nicolas Cage. Toby "Radiation" Fox evidently included this as a joke, but Andrew Hussie nonetheless gave it a place Homestuck via a bonus page.
- Homestuck Vol. 9 features the first of two works by Team Dogfight, a collaborative music group consisting of David "Dirtiest" Dycus, William Ascenzo, Mai "konec0" Yishan, DJ Sai Tae, viaSatellite, and Ian "myusernamesmud" White. Many members of the team were prominent Homestuck fan musicians prior to the release of the album, with a number of their tracks featured on the Land of Fans and Music fan album. Others appeared during the official music contest that led to the creation of the two previously released coloUrs and mayhem albums.
