Hard Rock Hideout has uploaded video footage of CINDERELLA's June 19, 2010 performance at the M3 Rock Festival at the Merriweather Post Pavilion in Columbia, Maryland. Watch the clips below.CINDERELLA played its first show in over three years on March 19, 2010 at the Grizzly Rose in Denver, Colorado. In a recent interview with Bring Back Glam!, Tom Keifer spoke about his voice issues which forced the cancellation of CINDERELLA's U.S. tour with WARRANT, LYNCH MOB and LYNAM in the summer of 2008. "The root problem with my voice issues started in 1991 when I was diagnosed with a paresis, [which is] partial paralysis of one side of my voice box," he explained. "You have to train it to learn how to sing again. "The partial paralysis is a neurological thing and it's caused by viruses, even a common cold virus. The virus gets into the nerve and it can degenerate it. It's rare, but it happens. Once degenerated, you can't — there's no surgery or medicine that fixes it. You have to retrain it and it is very tedious and time-consuming and it's not a lot of fun. In a lot of cases, it is career-ending. "The singing voice is such a fine tuned instrument and any subtle change can throw it off." He added, "A year ago, I met the 'Miracle Man' who is a vocal coach. He really taught me a lot of things about breathing and how to control my air and how to prevent this from happening again. I've been studying this technique — it's what they teach opera singers — classical voice training, which I've never been trained that way before. It doesn't change the tone of your voice, just how you support it. I still sound the way I sound but I'm not hurting my voice, and it's really worked and my voice feels stronger." Regarding the possibility of a new CINDERELLA studio album at some point in the not-too-distant future, Keifer told AOL's Noisecreep, "We always feel like a band when we get back together and tour so the plan right now is to not put any pressure on ourselves and to just get back out and have some fun, do shows and be a band again and we'll see where it leads. It's definitely a possibility we could make a record at some point, I just don't know when that would be. I would say it's gotta be right place, right time. It's gotta feel right."
