Yep, D.C.'s Dischord Records is now available at eMusic.Their more prominent bands and their albums can be downloaded from my own favourite digital download service, eMusic.
You heard of Fugazi, now hear them [for free!] by going here. Minor Threat, Jawbox, and Rites of Spring are just some of the famed bands you will find.
Also recently added is Brendan Benson's great debut album One Mississippi reissued with Benson's EP The Wellfed Boy... that's 22 tracks from this criminally ignored indie pop singer/songwriter. You will also find Q and not U's No Kill No Beep Beep.
Check these and get them free [if you are eligible... i.e. not yet a member] by going here.
