Don Zientara: Don Zientara is an American record producer and musician.  He owns and runs Inner Ear Studio in Arlington, Virginia, located just outside Washington D.C., and is most widely known for his production work with Fugazi, Minor Threat and various other Dischord Records artists.

Fiasco (band): Fiasco was a Brooklyn-based trio formed in October 2005 by Jonathan Edelstein (guitar/vocals), Julian Bennett Holmes (drums), and Lucian Buscemi (electric bass/vocals), although all three are multi-instrumentalists.  They were known for their intense, high-energy music, their energetic live shows, and for playing off the venue's stage, in the round.  They drew influences from early 1980s hardcore punk bands such as Minor Threat, Flipper and Bad Brains, as well as more recent noise and indie rock bands such as Lightning Bolt, Fugazi, and Shellac, and math rock bands including Hella and Don Caballero.

The Faith (American band): The Faith was an early American hardcore punk band, from Washington D.C., with strong connections to the scene centered on the Dischord label.  Along with Minor Threat, The Faith were key players in the early development of hardcore, with a (later) melodic approach that would influence not just associated acts like Rites of Spring, Embrace and Fugazi, but also a subsequent generation of bands such as Nirvana, whose Kurt Cobain was a vocal fan.

Salad Days (film): Salad Days: "A Decade of Punk in Washington, DC (1980-90)" is a documentary written and directed by Scott Crawford.

Dischord House housed Dischord Records (founded a year earlier by The Teen Idles, shortly thereafter to be run by Ian MacKaye and Jeff Nelson).  Despite its terribly low ceiling, many DC punk bands practiced in its basement over the years: Minor Threat, Skewbald, Iron Cross, The Faith, Second Wind, Rites of Spring, Embrace, Three, Fugazi, Beefeater, Fidelity Jones, Happy Go Licky, Kingface, One Last Wish, The Evens.

Dischord Records discography: Dischord Records is a Washington, D.C.-based independent record label specializing in the independent punk music of the D.C.-area music scene.  The company is co-owned by Ian MacKaye and Jeff Nelson, who founded the label in December 1980.  Before founding Dischord, both MacKaye and Nelson were members of the Teen Idles, and the label was initially meant to only foster a single release from the defunct band, the "Minor Disturbance" EP.  By the time Dischord #1 was finished, many new bands had emerged from the same music scene, and like the Teen Idles, also began releasing their records through Dischord.

The Evens: The Evens are a Washington, D.C. indie-rock duo, formed in the fall of 2001, comprising partners Ian MacKaye (guitars, vocals) (of Fugazi, formerly of Minor Threat) and Amy Farina (drums, vocals) (formerly of The Warmers).  After Ian MacKaye's band Fugazi entered a hiatus, The Evens began practicing extensively, and eventually played a few shows and recorded a self-titled album, released in March 2005 on MacKaye's label, Dischord Records.  The Evens are known for their unusual choices in venues for performances and the stylistic change from what many have dubbed the "D.C." or "Dischord" sound. " The Washington Post" has described the sound as "what happens when post-hardcore becomes post-post-hardcore."
