their first album written, recorded, and mixed in its entirety at the studio room; previously they had to write in an adjoining space. Having the group work in their own space without the additional pressure of booking studio time and fees resulted in a more relaxed environment. They were joined by engineer Hugh Padgham, who had also worked on Abacab, but this time carried out production duties themselves with Geoff Callingham offering technical assistance. Rutherford recalled an initial period of slow and sluggish progress, but after a particularly productive session on the third day they had "two or three" songs worked out, which increased their interest and excitement towards the album and in performing the new material on stage. Before the sessions began, the group considered the idea of Banks or Rutherford taking on a lead vocal on the album, but opted out as they had developed material with Collins's voice in mind. Banks said that he and Rutherford take a more prominent role in the backing vocals on Genesis than previous albums. Banks explained the album was the result of the group's decision to "write an album and record it in one go, from start to finish". The group considered their strongest material had been put together collectively, so they decided to make an entire album in such a way as opposed to developing someone's pre-arranged ideas. Before, each member would contribute fully or partially arranged songs, which restricted development or suggestions from the other members. This time tracks came about through jamming and improvisations in the studio that were recorded onto tape, ensuring the band remained unified and kept songs fresh. Banks noted that this made recording more exciting and spontaneous. This collaborative effort marked a return for Genesis crediting each member for writing the album as opposed to listing individual credits, which they had not done since The Lamb Lies Down on Broadway (1974). The collaborative effort also had an influence on the album's title as the group were unable to come up with a suitable name, so they used Genesis to emphasise the fact that it was written collectively. The main keyboards that Banks used on the album are the Prophet 10, Synclavier, an E-mu Emulator, a Yamaha CP-70 electric grand piano, and an ARP Quadra on "Mama". At one point on the album, a sample from the soundtrack to 2001: A Space Odyssey (1968) is
