Matt Hollenberg is one of the most adventurous players around right now, and he’s got a lot going on. He’s a member of John Zorn‘s trio Simulacrum, along with organist John Medeski and drummer Kenny Grohowski. He’s also a member of the band John Frum, with Liam Wilson of the Dillinger Escape Plan and some other underground metal folks. He’s also just launched a new instrumental metal fusion project called Shardik , and his longest-running band is Cleric. They’ve been around for more than a dozen years, but they’ve only released two albums, one of which, Retrocausal, just came out. Apparently, though, they’ve got two other records in the can, one of which is entirely made up of Zorn compositions, from the Masada songbook.
