Martin Bisi is a repeating rock 'n' roll footnote: He recorded early albums by Swans and Sonic Youth, worked with Bootsy Collins and Whitney Houston and helped jumpstart John Zorn's Naked City and Bill Laswell's Material. Thanks to the recent resurgence of young New York bands vested in the dark and heavy, he and his aesthetic have enjoyed something of a resurrection. His new Ex Nihilo is his first solo album in five years. Like a house of horrors haunted by a medieval choir and a free jazz band that delights in fright, Ex Nihilo is an hour-long crawl through sinister madrigals and malevolent soundscapes. It's a fitting if fitful encapsulation of Bisi's legacy. Caltrop headlines with its raised-in-the-sun Southern anthems. Chicago duo Invisible Things, who open, sculpt a thousand guitar pricks, long electric roars and ever-roiling drums into short-lived but nevertheless colossal waves of sound.
