Serum is a series where we invite talented electronic music producers for a temporary creative collaboration. For the fourth edition we are glad to share three timeless pieces of deep dubbed out techno by Mohlao (aka Multicast Dynamics, VC-118A). The record is then completed by an atmospheric tribal interpretation by Dorisburg. By uniting these newfound friends of ours, we welcome the new solar cycle and wish everyone a healthy and prosperous venture toward summer
