Ty Segall and Tim Presley aka White Fence become one once again, regrooving their collaborative project that produced 2012's Hair. Joy finds the dyphrenic duo caught up in the commencement of on-beyond rock; music made with the old tools, but emitted from a fresh new, single-celled organism. This time, the old "one and one make one" line does not apply. Hair had the quality of emulsion – drops of Segall suspended in Fence; a compound of White dispersed over sheets of Ty. With Joy, Tim and Ty arrive without traveling from the same place, occupy one single headspace, finishing the other's phrases, pulling licks from each other's places, and singing as one. Joy is their own sound of today, a shared individuality, prisming all possible stances into an unseamly metastasis that flows for 15 ebbcentric tracks.
