Lorenzo Esposito Fornasari aka LEF is a vocalist and composer from BolognaItaly. Over the last decade he has had notable collaborations with Bill LaswellHamid DrakeNils Petter MolværEivind AarsetJamie SaftPat MastelottoEraldo BernocchiMarkus StockhausenTony WakefordTrevor DunnGiovanni Lindo Ferretti, Raiz, QuintorigoCristina Donà, Gianni Maroccolo, Ambrogio Sparagna, Faraualla, Simone Zanchini, Enrico Gabrielli, Mariposa, Sigillum SEphel Duath and Fabrizio Puglisi.

Comprised of monstrously prolific Zu bassist Massimo Pupillo, Sigillum-S founder and noted experimental guitarist Eraldo Bernocchi – whom you may also know from his Mick Harris collaborations – drummer Balázs Pándi, and shapeshifting vocalist Lorenzo Esposito Fornasari, Obake operate in the twilight area between ‘art’ and sludge. Fornasari’s contributions in particular firmly place the music herein into the bracket of ‘art’ – he soars operatically above and through the music, then plummets down into the lower registers to intone, command, insinuate, mutter, howl and screech like a thousand chattering apes. His hollow, tombstone-scraping croak is the equal of any ‘Brutal Death Metal’ grunter, and his powerful baritone like a dark twin to the similarly gifted Mike Patton. Indeed, hearing his voice across the course of Obake, one could very easily believe that he was the mutant offspring of Patton and Attila Csihar – the demonically-throated voice of Sunn, Mayhem, Void Ov Voices and Aborym – so fluid, stentorian and damned dark are his tones, and, like Patton, he doesn’t merely sing – he vocalises, using his voice as an instrument for adding layers of texture. Fornasari elevates what would already be a seriously tasty musical proposition into a must-hear.

That said, the music on this record is pleasingly varied and often marked by a profound sensitivity. Fornasari’s vocals, in addition to the metallic tinge, cover textures ranging from Leonard Cohen’s vaguely menacing whisper, to the darkly elegant style of Secrets of the Beehive (Virgin, 1987)-era David Sylvian, to full-blown operatic exaggeration (“Dream Made of Water”)

La scrittura non è impresa facile, affidata a Lorenzo Esposito Fornasari, che esce a testa alta dal labirinto di ambienti sonori richiesti dall’Opera: rock, musica da camera, canto epico, tra citazioni di Beethoven e canto in latino.
—SAGA reviews on ilsussidiario.net
Fornasari’s vocals are astonishing powerful, morphing between an urbane Sylvian-like drawl to a cracked-gravel growl oozing with a creeping malevolence. That theatricality evokes the dystopian pronouncements interleaving Bowie’s Outside.
