Savatage continued to focus on their Trans-Siberian Orchestra project for a while, releasing "The Christmas Attic", but the release of "Poets and Madmen" in 2001 was highlighted by Jon Oliva's return as lead vocalist in studio, replacing Zak Stevens, who left the band citing family reasons, and the departure of Al Pitrelli, who accepted an offer to join Megadeth in 2000. Pitrelli did record solos for some songs prior to his departure. Another very limited US tour followed, supported by Fates Warning in the early shows, and then Nevermore for the remainder. Around this time, Caffery chose Zak's replacement in the form of the singer Damond Jiniya (Diet of Worms), who was once again brought to the band from long-time friend and Circle II Circle manager/co founder Dan Campbell. Damond sang the song ""Edge of Thorns"" as his audition song. Damond performed Zak's parts on tour, with Jon having an increased vocal role in proceedings. Jack Frost auditioned for the role of rhythm guitar player, and got the gig. He played with the band for a majority of the tour, but was mysteriously asked to leave the band after the tour, although it could be said that Frost's commitments elsewhere drove him from the band. For Summer festival appearances in 2002, the band was joined by Annihilator's Jeff Waters.
