rosay is not the only pipette pursuing a solo career. 
few years ago gwenno had a mini album rumored to be produced by the postal service or at least influenced by them. it wasnt that bad at all, but it had no response. check it yourself. 
she is still in the band with her sister ani, but shes dj-ing as well.
and she made an apperiance in the video for PNAUs next single.
