The artists partnered up following an exchange of DMs last year after Rose's breakout, certified platinum hit 'B.O.T.A (Baddest Of Them All)' with Interplanetary Criminal.
The DMs led to studio sessions which have now culminated to the disco-infused, horns and funk-laden 'Body Moving'. Following initial sessions, a performance at Harris' Ushuaîa Ibiza show last summer from the 'B.O.T.A' star marked when the duo decided to finish what they had started working on in the studio.

Rose expressed her disbelief in working with one of dance music's biggest stars, noting that their collaboration was "something I never thought would be possible."
The last 18 months have marked a meteoric rise for the East London native, where she has gone from respected to UKG and house DJ and producer to world-renowned singer, featuring on tracks with Mura Masa and the Martinez Brothers.
"We have created something I believe has really combined our two identities into something unique and also reflective of our own personal work."
Harris agrees, highlighting his excitement to get the track out and underlining how "amazing" Eliza is to work with.
When the two came into the studio, the goal was "to create a track that captures the essence of summer while also igniting the dancefloors," according to the Rosebud Recordings boss.
