As far as singers, Jack was able to mold and create  the sound he wanted from the vocalists to be an appropriate compliment  to his guitar playing and for each song. Take for example “Hell or High  Water” done by Jersey's own Alan Techio of Hades, a darker tune, a  little modern sounding without being trendy and even Jack wrote the  music sounding very similar to Alan's old band Non Fiction. For “Wasted  Love” sung by Ted Poley from Danger Danger, he brought out the best  side to Ted that most have never heard, now he sounds more ballsy,  stronger, and was able to hit and hold very strong notes. 
                          “Crucification”,  sung by Neil Turban is full on classic almost Speed Metal in nature  with Neil turning out some screaming vocals reminiscent on his classic  work on “Fistful of Metal” from Anthrax. “Covered in Blood” has some of  the most paint peeling high pitched screams I have heard in a while  done by Jeff Martin from Racer X and at first listen I thought of the  80's band Nitro, that's how psychotic he sounds. Jack also delivers and  equally interesting guitar solo. 
                          “Out  in the Cold” features Terry Illous from XYZ and has a very singable  chorus and a definite pseudo Dokken feel, all ready for radio. One of  my favorites is a cover of “Sign of the Gypsy Queen”, originally done  by April Wine, again features Ted Poley giving another solid  performance and a track very suitable to his voice. The chorus and  vocal harmonies are the highlight. “Hold on Loosely” by 38 Special is  tackled vocally by Jack Frost himself. Both tracks contain a ton of  melody, both in the chorus's as well as coming from the slew of guitar  harmonies. 
                          Other contributors to the  music are Joey Vera of Armored Saint, Mike Lepond from Symphony X, and  Mike Duda from Wasp playing bass, and Patrick Johansson from Yngwie's  band playing drums.
