On 1 August 2006, he revealed his next solo project would be named "Awakening of Aggression" and confirmed the music would be "heavy" and "hard-hitting." When interviewed, Klepacki said that he channeled stress into the heavy music of the new album. "Aggression" was released in October of the same year, and was made available on iTunes on 7 December. He filled the liner notes of the album with the names of several supportive fans who had purchased his music. As of April 2007, he speculates that a new solo release will be ready by the end of the year. After establishing recognition on "Ultimate Fighter", Klepacki began scoring themes for HDNet's "Inside the MMA" and "HDNet Fights" in autumn 2007. Around this time, he made it to the district finals of the Guitar Center "drum-off" competition after winning two store challenges in Las Vegas but was eliminated. His solo album "Infiltrator" was released in April 2009. According to Klepacki, the album was inspired by his recent work on the Red Alert series. Klepacki enjoys Las Vegas thanks to its diversity of musical talent and prolific number of shows and attractions. He attributes his showmanship to being raised in the city, noting that one has to "stand out" to be noticed among the entertainment atmosphere of Vegas. The city's "Las Vegas Weekly" honored him as a "badass composer" in its mid-April 2009 issue, highlighting his prolific fan-base and work as producer for various local bands.
