Please answer the following question: What is the name of the band that I.R.S. allowed to return to North Carolina to record "Pilgrimage" with Easter, as well as producing partner Dixon?  Answer the above question based on the context below:  R.E.M. recorded the Chronic Town EP with Mitch Easter in October 1981, and planned to release it on a new indie label named Dasht Hopes. However, I.R.S. Records acquired a demo of the band's first recording session with Easter that had been circulating for months. The band turned down the advances of major label RCA Records in favor of I.R.S., with whom it signed a contract in May 1982. I.R.S. released Chronic Town that August as its first American release. A positive review of the EP by NME praised the songs' auras of mystery, and concluded, "R.E.M. ring true, and it's great to hear something as unforced and cunning as this."I.R.S. first paired R.E.M. with producer Stephen Hague to record its debut album. Hague's emphasis on technical perfection left the band unsatisfied, and the band members asked the label to let them record with Easter. I.R.S. agreed to a "tryout" session, allowing the band to return to North Carolina and record the song "Pilgrimage" with Easter and producing partner Don Dixon. After hearing the track, I.R.S. permitted the group to record the album with Dixon and Easter. Because of its bad experience with Hague, the band recorded the album via a process of negation, refusing to incorporate rock music clichés such as guitar solos or then-popular synthesizers, in order to give its music a timeless feel. The completed album, Murmur, was greeted with critical acclaim upon its release in 1983, with Rolling Stone listing the album as its record of the year. The album reached number 36 on the Billboard album chart. A re-recorded version of "Radio Free Europe" was the album's lead single and reached number 78 on the Billboard singles chart in 1983. Despite the acclaim awarded the album, Murmur sold only about 200,000 copies, which I.R.S.'s Jay Boberg felt was below expectations.R.E.M. made its first national television appearance on Late Night with David Letterman in October 1983, during which the group performed a new, unnamed song. The piece, eventually titled "So. Central Rain (I'm Sorry)",...
