(KFJC) In an inventive, sparse meeting of two musicians, this album showcases Ron Heglin, who provides the voice, and Tom Djll, providing the rungler playing. Heglin sings with an imaginary language of his creation, his voice playing the role of musical instrument, since his words have no meaning to the listener. His invented sounds interweave with the runglers played by Djll, “rungler,” meaning an instrument invented by synth builder Rob Hordijk that creates short stepped patterns of variable length and speed. Djll plays three types of runglers on the album. Together, they explore the contrasts and harmonies possible between the instruments’ discrete, synthesized, relatively pure tones and the sounds of an improvised human language with its messy rich tones. - Isotope

(Vital Weekly) Looking at the title of the CD, I take it that Djil plays the runglers, a word I had not heard before. This is a disc of voice improvisations and electronics, and it’s not some (alternative) pop music, but sound poetry. For many years, I tried and tried, but sound poetry remains one of those things that’s not my thing, and, in general, voice improvisations (what’s the difference?) are things I find rigid to engage with. The blips (or is that ‘blippo’s?) and blops of the modular set-up are in tune with the voice approach here, jumping around, chaotically moving around, following and contrasting the voice, and such a combination that works very well. As with many things from the improvised music world, I can imagine this works well in a concert situation. I witnessed quite a few concerts by Jaap Blonk, and he’s quite the expressive performer, and it’s that sound poetry in action I quite enjoyed.. I don’t know if Ron Heglin is along those lines; his performance is not as expressive, but relatively civilised, and the modular is what takes this into something extreme, while keeping it well under control. This is not noise music, but rather something more of a classic electronic approach. - Frans de Waard

(Felthat Reviews) Ron Heglin and Tom Djll have created not only an interesting outlets to present their talents on this cd but also introduce unassumingly how you can create different climes and chimes and effortlessly blend non -invasive electronics and voice in a way that it sounds both familiar and otherworldly. Released as a digital download and a cd by SF's Public Eyesore this album compiles 9 tracks which are meandering effortlessly from one to another without too much hassle and difficulty being brilliant examples of how sound - both electronic and in a form of human voice can be so approachable and transparent. The production here plays and important role and great mastering too. It makes the sound almost touchable as if both Ron and Tom are sitting next to you - listening to their compositions makes you feel more present and quite naturally forces you to feel this music and be attentive. - Hubert Heathertoes

(Disaster Amnesiac) Kind of scary, really, the way in which Ron Heglin and Tom Djll immediately begin the sounds of Duos for Voice and Runglers, their recent CD release on Public Eyesore Records. Deeply singular abstraction is the main menu item on this one, and they serve it up hot from the start. If one figured that a recording made up of sounds produced from "chaotic circuit[s]" as their foremost feature and improvised vocals in a personal language could possibly be a bit terrifying, one would in the cases of most people be correct. Disaster Amnesiac can't say that I was scared exactly, while listening, but more summoned to attention. This latter may have to do with the fact that Ron Heglin and Tom Djll are known qualities to me, as far as listing to music goes; the depth of their musical explorations is at the very least familiar to these ears. Along with the sounds aspect contained within this duo, there is also, dare I say, an intellectual gravitas to them. Put a bit more simply, they're serious about this stuff. Anyway, that's the way that they both came off to me, and fucking hails for it. Yes, the music produced on documents such as Duos can supply the simple fun of diversion from whatever else is occurring in a human life, but along with that ideas are attached. Specifically from Heglin: his performances and cover art contributions explore, with intent, aspects of language and its manifestation within the human experience. He goes deep into too. As stated, dude's serious. The Runglers which Djll utilizes and describes as both precise and unpredictable serve as either a foil or a mirror for the human sounds from Ron. As the latter relays ancient sounding stories from alternate dimensions, the former pushes his instruments into sharp, cutting, and mostly harsh bursts of Noise. What's been striking to Disaster Amnesiac is the absolute control of the sounds which have arrived. Hints of possibly more ambiguous results are given from the press sheet for Duos, but it sounds so very controlled in these quarters. Especially fine is bakinsa, in which high skilled throat singing emerges from the throat of Heglin. Adding to the concision is the relative brevity of the entire disc and its nine tracks. Nothing drags on for too long and that's fine. If you're up for putting in forty five minutes or so of mental effort, you'll not find Duos for Voice and Runglers that intimidating, at least not for too long. - Mark Pino

(Babysue) Also just released is a CD entitled Duos For Voice and Runglers by Ron Heglin and Tom Djll. Difficult to easily explain and having a sound that is quite unlike anything else out there, Heglin and Djll are treading in territory that will be unfamiliar to almost everyone. This is one you need to hear so you can come up with your own comparisons and/or explanations. Strange stuff, definitely not intended for those who like their music samey and familiar (haw!). - Don Seven
