2006, VH1 premiered the documentary titled DMC: My Adoption Journey. The program ends with McDaniels reuniting with his birth mother, who turned out to be named Berncenia and despite previous beliefs, was not, in fact, of Dominican descent. He thanks her for her choice because had he not been placed for adoption, Run-D.M.C. would have never existed. In March 2006, McDaniels released his solo album, Checks Thugs and Rock N Roll. Produced and Music Directed by Romeo Antonio. The first single, "Just Like Me", features an interpolation of Harry Chapin's "Cat's in the Cradle" (1974) performed by McDaniels' musical savior, Sarah McLachlan. During a recording session, McLachlan revealed to McDaniels that she, too, had been adopted. McDaniels also collaborated with Adoptee Zara Philips on "I'm Legit." He testified before the New Jersey State Legislature in support of legislation to restore adopted adults' access to their original birth certificates. The legislation McDaniels supported was signed by Governor Chris Christie and became effective on January 1, 2017. As a New York born adoptee, however, McDaniels did not have access to his own original birth record---he hired a private investigator to help find his birth family in New York. McDaniels had written the first draft of his autobiography before learning he was adopted and was working on a second solo album, working titled The Next Level. Three tracks off the new album have been released ("Next Level", "Hip Hop", and "Beef Eater") and can be heard on his Myspace page. In June 2007, McDaniels joined Aerosmith on stage at the Hard Rock Calling festival in London, England to perform "Walk This Way". McDaniels is featured in the video game Guitar Hero: Aerosmith (2008) singing Run-D.M.C.'s singles "King of Rock" and "Walk This Way". He is also an unlockable guitarist in the game. In the game's trailer, it is revealed that McDaniels' son plays Guitar Hero for hours each day. In 2009, McDaniels performed in The People Speak, a documentary feature film that uses dramatic and musical performances of the letters, diaries, and speeches of everyday Americans, based on historian Howard Zinn's nonfiction book A People's History of the United States (1980). McDaniels' second solo album, the more rock oriented The Origins Of Block Music, was due out in mid-2010 but was delayed. In December 2010, McDaniels appeared with Talib Kweli, Mix Master Mike, and Ahmet Zappa on a cover of Frank Zappa's "Willie
