Timeline:
Early 2011 - Tom Schleiter (guitarist) leaves band to "focus on songwriting and producing for other artists full time." Schleiter was the co-writer to all the songs on their debut along with Max Perenchio. I think Perenchio, though, is the brainchild behind Bad City.
June 27 2011 - Josh Caddy (vocalist), due to a "very serious personal conflict" with other members of the band. Josh had no writing credits but seemed like a good frontman. Replaced by ex-Powerspace vocalist, Alec Cyganowski. Apparently he's a high pitched screamer - i.e., Freddy Mercury. Pretty animated. Bad City was comprised off all ex-Powerspace members so this looks like a reunion of sorts.
July 18, 2011 - Tour wraps up. The shows June 27-July 18 were completed with Cyganowski on vocals.
October 13, 2011 - Kiss Kruise.
