Once demos sessions concluded, Scorpions sent their demos to producers they wished to work with. At the top of their list were: Bob Rock, Rick Parashar, Max Martin, Dieter Dierks and Erwin Musper. Rock was on vacation and resting after the two-year production of Metallica's album "St. Anger"; Dierks was scrapped after a financial disagreement between him and members of Scorpions. They finally chose to work with Musper and booked the studio for 15 October 2003. However, they were not ready for recording because they did not have a bass player, and none of the auditioned bass player had had access to the demos recorded by the band. Since there were no bass player during the demo sessions, all bass lines had been laid down by Jabs. Kottak invited Jeff Pilson and Jimmy Bain for the recording sessions, but scheduling clashes prevented their attending. Five days later the band entered the Peppermint Park Studio in Hannover, Germany, and after four to five days of setting up the equipment, they started the recording process, still without a bass player. Schenker's assistant recommended Polish bass player Paweł Mąciwoda. He learned the bass parts from the demos and was in the studio on the first day of recording. After three days, he had recorded a total of 11 songs. After those recording sessions were finished, band members did another recording session with Barry Sparks on bass, recording 5 songs. Despite a total of 16 recorded songs, the band still felt they were missing some songs to complete the album. At the very end of the recording sessions, Shenker came up with the song "If You Could See Inside My Eyes" (which became "Through My Eyes" on the album), Meine presented "Maybe I, Maybe You", Kottak "Can You Feel It" and Jabs "This Time". After those 4 songs were recorded, finally the band had a foundation of 12 songs to make an album.
