The main challenge was to stay within the parameters of the drums – either that or we would have to re-record them again. So I had to be very creative to make the songs interesting without introducing new sections or tempo changes. This is why there are so many harmonies and counter melodies. It was challenging – often I would just jam to the recorded tracks for a long time trying to find a different vibe then that already recorded... this is best apparent on To the Bitter End or Tunnel Effect. If you listen to both guitars, they're doing widely different things yet each other really well." The title of the album was initially "To the Bitter End" as the band intended to "record, or mix, or master until we're 100% happy and NOT settle for compromises". Bart explained that the artwork did not fit with the title so the band thought of a newer title and decided upon Defiant Imagination. Defiant Indoctrination, Live in Montreal (2005–2007) In 2005, Defiant Indoctrination, a triple DVD documenting a concert in Montreal on May 7, 2005, was released. Produced by Bart and Roxy, the first two DVDs featured the concert, in which Defiant Imagination was performed in its entirety along with various other tracks from previous albums, and the third DVD contained drum footage of the entire show, focusing entirely on Yanic Bercier. The mix was handled by Jean-Francois Dagenais (Kataklysm, Misery Index) and Bart. Several guest musicians were featured on the DVD including the famous Quebec cellist Claude Lamothe, Alex Auburn of Cryptopsy fame, bassist Dominique "Forest" Lapointe of Augury/Atheretic/Negativa, and a classical choir and violinist. In early 2006, William Seghers left the band in order to concentrate on Neuraxis and local progressive metal guitarist Marc-André Gingras of the MAG project was brought in to replace him. In summer 2006, Bart built his own home studio, 40 West Studio, and began working as a producer there with Roxanne as the studio technician. In November 2006, the official Quo Vadis forum was launched. In January 2007, Quo Vadis, along with Kataklysm, toured both Western Europe and Eastern Europe for the first time. On May 12, 2007, Quo Vadis released Live in Montreal, a live album containing the audio of the 2005 DVD Defiant Indoctrination. In November 2007, Bart released a guitar and bass tabulature book for Defiant Imagination and was sponsored by
