I just saw Silverstein, ADTR, august burns red, Enter Shikari, & Veara in concert. It was bada$$
Um I'm not sure what I would consider emo rock... I mean I might think it's different than what you are thinking. Some bands have an "emo-ish" song so... idk but here's what I would say
Silverstein most definately
From first to last
ADTR
Greeley Estates
The Starting Line
The Spill Canvas
Escape the Fate
Pierce The Veil
The Used
that's all I can think of for now
