Question: What year was the formation of the group that performs Reflexos da Noite?

full_context: Document 1: Purple Night: The album was the second in a short-term recording deal with major label A&M Records, who had a "Modern Masters Jazz Series" imprint going at the time. Sun Ra's profile had risen considerably in recent years, partially because of the support given to the master in interviews by avant-garde alternative rock band Sonic Youth around that time, who had both named him as an influence and opened shows for Ra and his Arkestra.
Document 2: Pantulan Cita: "Pantulan Cita" was released in 1981 by Musica Studios, with no singles. It was a critical and commercial failure, although the cover was well received. Along with "Percik Pesona" ("Stain of Enchantment"; 1979), it was Chrisye's only solo album to not receive any awards. Disappointed with the album's failure, Chrisye decided to go on a sabbatical. He would not record another album until "Resesi" ("Recession"), a collaboration with Jockie and Eros Djarot, in 1983. The later album was more successful, but followed then-popular trends in music.

Save for three of the songs which were co-written and co-produced, the entire album was written and produced by Hyper Crush.
