If you're into American punk, don't miss the DC episode of Sonic Highways

I am all about bad brains and minor threat. grohl has become quite an ambassador for rock music.
Minor Threat. Been a fan of theirs since I was 13. It's a shame they only had one album. Dag Nasty is the closest thing you can get to another album done by Minor Threat. The guitarist from MT is in that band, and you can hear MT's style musically. Even the singer's voice and style sounds like Ian at times.
