Eh there seems to be a tenuous line between the real like Fugazi Emotive Hardcore, and then the questionable things that could qualify as Indie Rock. But in my opinion, if you look at the musical patterns of Fugazi's softer songs they are mimicked but in a much poppier way by bands like Weezer, The Get Up Kids and The Promise Ring. Even their harder work has mainstream equivalents; take Getchoo by Weezer.
Anyway the Second Wave is an interesting debate point regardless.
Who else was feelin "I have dreams" from florida? I was way into their demo.
PS: if anyone has any hand silkscreened posters for saetia/you&i/jffb/books lie/off minor or early second nature/level plane/magic bullet type bands I would love to talk buy or trade. Cheers.
