Is it worth it?

I haven't figured out if it's worth buying tickets to Soundwave Revolution for the soul purpose of seeing Hole play live. Other then that I'm not fussed about seeing anyone else, except maybe Sisters of Mercy, but even then not really. Theres some totally un-ironic hair metal I may be able to psych myself up for as well Dashboard Confessional who I recall were actually ok. Oh and Primus are playing too, who i'd see for sure.

Someone needs to explain to me the difference between soundwave and soundwave revolution though, assuming I do decided to blow $166.30 on one band that would totally be worth the money.
