Between February and August 1985, Sade enlisted the same team of producers they worked with on
Diamond Life. The band co-produced
Promise with
Robin Millar,
Mike Pela, and Ben Rogan, the latter of which played a less central role in the production. Some of the album's sessions took place during a two-week sojourn in
Provence, utilising an
SSL E-series console housed at the barn-shaped, concrete-built
Studio Miraval. However, the majority of the album was recorded at
Power Plant Studios in London, where the project commenced in February 1985 and concluded seven months later, with the mix being done in the Gallery (Studio Three) located on the top floor, with its 44-channel
Harrison MR3. Studio One is where the production team initially listened to several of the songs in demo form, although Pela was at the
Royal Albert Hall when he first heard one of the new tracks. Like their debut album,
Promise was recorded live, though it featured the use of technology, sampling drums by way of an AMS with a lock-in feature. The album's lead single was created at Power Plant's Studio One, where a 30 × 25 × 18-foot live area was complemented by a 36-channel Harrison Series 24 console,
UREI 813B main monitors and a 24-track
Studer A820 recorder running
Ampex tape at 30ips. Pela explained the process saying, "We had UREI monitors in all of the rooms so that there was some continuity, and we also had Acoustic Research AR18Ss, which we discovered at that studio and which I've still got a pair of. They were like hi-fi speakers, they only cost about 80 quid, and once we'd started using them the company stopped making them. They were really nice and natural-sounding, not designed to carry super-low heavy frequencies, but absolutely fine." ==Release and promotion==
