http://www.project-imas.com/w/Official_List_of_ConcertsI made this a few minutes ago.. I don't know much about iM@S concerts but this is defenitely a section worth expanding on IMHO. So, if anyone knows anything, it'd be great to at least get a few sources besides dengeki...
Also, THE IDOLM＠STER 4th ANNIVERSARY PARTY SPECIAL DREAM TOUR’S!! is going to have all of those concerts in that specific section, since there were alot of them.
