The most prominent rock band to have dabbled in dstep is Korn. In 2011 or 2012, they made an album where each track was a collaboration with a dubstep producer or two. As someone who likes dubstep, IMO, the whole thing really, really sucked. Mostly because I don't like Korn or hard rock music in general, but, in a way, the whole affair was also just kind of sad. It was Korn trying desperately to stay "relevant" or whatever As for LP, dubstep remixes are fine (many would say that dubstep remixes of Korn songs would've been preferable to rock/dubstep originals) but I'd personally prefer they kept away from blatant EDM references in their original songs.
