On their first EP, the Californian group of Purge Solenoid demonstrate their oddly-flavored take on prog rock, coming off as something like Zappa fans with less emphasis on the guitar.  The weird vocals don’t hurt that impression, but the drummer’s whole-hearted attempts to steal the show do pull the group further in other directions, and the slather of psychedelic effects on the strings help gel a firmer sense of the group’s own character with their bouncing fervor.  Twists through stronger jazz riffings, along with use of the guitar to under- and counter-score the drums’ rhythms. give the music a nicely dizzying effect, and the band’s confidence to close with a ~9-minute song (”Nebulous”), it made all the more appreciable by their talented execution of it.  A very impressive debut, with lots of little details to pick out and savor in repeated listenings.
