“Siren 042” follows the September 2018 release of Lala Lala’s critically acclaimed album The Lamb. Of the collaboration, Lala Lala’s Lillie West says, “Yoni [Wolf] once talked me down when we were on the the strongest LSD of my life and I claimed to be ‘drowning in a river of sadness.’ I text him when I’m sick. Is he my life coach? Seems that way. I am a WHY? super fan and making this song was a dream come true. I hope to trick him into letting me into his home and more collaboration soon.”
