The Dillinger Escape Plan/YMMV

Broken Base: Fans are split between those who appreciate more or less everything they've recorded, and those who think everything they've done since the EP with Mike Patton has been an artistic failure.
Epic Riff: The opening riff from "43% Burnt" is probably the first thing that comes to mind when they're mentioned; it's one of the few musical ideas in their back catalogue that could be called "catchy". Little wonder that they've played the song at every gig they've played since they wrote it.
Magnum Opus: Calculating Infinity is generally considered this, or at least, it's the only Dillinger album that all of their fans agree is good. It's also undeniably the most influential.
Magnum Opus Dissonance
Rescued from the Scrappy Heap: Fans were not pleased with the announcement that Greg Puciato was to be the band's full-time singer, especially given his "meathead" appearance and decidedly obnoxious persona, but he's gradually earned a lot of respect over the years.
Serial Escalation: Their live shows. Improvisational pyrotechnics, singer defecating onstage, thousands of dollars' worth of instruments destroyed, singer running across the audience's heads, teeth getting knocked out and feet getting broken by flying guitars, guitarist playing parts of a song upside-down while hanging by his legs, singer doing likewise... the list goes on. Bassist Liam Wilson once jokingly dubbed the band "The Dillinger Insurance Plan" because of all the injuries the members have sustained because of this.
Tough Act to Follow: Calculating Infinity. Much of the experimentalism on it's follow-up, Miss Machine, was there specifically to avoid accusations of the album being "Calculating Infinity 2".
