Polish label Zoharum take a very deep dive into Justin Wright’s exquisite solo guitar psychedelia with this sprawling 2xCD collection of various limited Expo '70 releases. For the most part, these extended pieces have a very drone-based and cosmic bent, but the two 2009 collaborations with Umberto's Matt Hill are legitimately transcendent and entrancing epics of slow-burning space-rock nirvana. Giving those two pieces a well-deserved second life is unquestionably Mother Universe's raison d'être, so the remaining pieces are more for devout fans and completists (though they are also quite good in their own right). The various physical formats all compensate for potential Expo '70 overload in their own ways, however, making it very easy to alternate between experiencing Mother Universe as a concise distillation of some of Wright's finest work or as an immersive and extended lysergic plunge.
