The album, which is available through iTunes and ShopTNA.com, includes nine songs. Featured is Hardy's current wrestling entrance theme, which is also titled "Similar Creatures."
TNA says the songs were recorded by Hardy and Dale Oliver for Embrangle Publishing Company and TNA Knockout Music in Tennessee.
The next project is Hardy's "first all original music project with Oliver and his band that is set for release in mid-2013, accompanied by his original art work that reflects the musical compositions."
The announcement seems to indicate that Hardy is staying with TNA after his current contract expires. Hardy noted in an interview one month ago that one of the deciding factors in whether he would stay with TNA was his music.
"In January when that rolls around, I’ll make a decision. I’ve pretty much made that decision," Hardy told the Busted Open satellite radio show about his contract status. "The music is going to be a huge part of it as far as keeping me around. We haven’t signed anything yet, but we are getting close."
