There are definitely better electronic acts out there. Groups get so much hype off of a couple of "hit" songs, that by the time everyone realizes they arent that great, the damage has been done. At least there are acts out there that actually plug in there gear. Underworld and Pnema Trio are two off the top of my head that do electronic music live, and good. When i saw Justice earlier this year at Sonar, i was expecting a DJ style set, and thought that was what they were doing. Didnt realize they were just mashing random buttons to look cool.
And Sonick, i used to be really into DJ mixes, and have also heards hundreds that are better than Justice as well. The appeal for me to see them, was they were going to be mixing their own songs. DJ's who dont produce absolutely have to rely on mixing skill, because they dont have the luxury of having an original set of their own music. But to do what Justice did, its just lazy. Justice exists outside of the magical "third song" realm, that is the bread and butter of mixing. I almost feel tricked, i really thought they were mixing it up. They at least looked like they were. With their lit cigs and their Frenchness.
