"For some reason SADO NATION has never gotten the same cult caché as fellow Portland first-wavers the WIPERS, the RATS, or the NEO BOYS. Hell, even avant noiseniks SMEGMA have more of a worldwide following for their demented mutant freewave than SADO NATION has received for their catchy, energetic punk rock. This is the band that kicked off the legendary 10-29-79 compilation, but people seem to talk more about the sole recordings by the even more unknown LO TEK than SADO’s ripping “Johnny Paranoid” that opens the album. But it seems the tide is changing on this, as their triple-digit Killed By Death collector wrecker records have been slowly seeing legit reissues. Disruptive Patterns is interesting, as it is an unreleased 1981 album that has now been issued twice by two different labels with two different covers in the last ten years. This version is by Puke n Vomit, and contains the original nine-song LP as well as three unreleased demo tracks from 1983, along with liner notes by members Leesa Nation (vocals), David Corboy (guitar/vocals), as well as Portland punk notables Jerry A. and Mark Sten. Musically, it’s high-powered punk of the time, fast and straightahead rockers, not dissimilar from anything in the West Coast first wave before hardcore reared its shaved head. The guitar fires off amped-up CHUCK BERRY riffage while the drums crash and tumble in full 4/4 force. Leesa and David trade off vocals from song to song, with Leesa more spit and sneer desperation and David’s voice a more melodic rock’n’roll shout. While not as much of a stone Portland punk classic as Is This Real?, Pick Your King, or In a Desperate Red, it’s still a document of the early Portland scene for any regional completists."
