Dewanatron on Rhizome

Pictured: "Leon and Brian Dewan Playing the Dual Primate Console"

"Homebrew Electronics is a new series on the Rhizome blog. For these posts, I will be conducting studio visits with artists and inventors who create unique electronic instruments.

Last week, I met with cousins Brian and Leon Dewan of Dewanatron at Leon’s apartment/workshop in New Rochelle, NY. I first encountered their whimsical, one-of-a-kind instruments at a solo exhibition at Pierogi Gallery in Brooklyn a few years ago. Not only do they produce and exhibit their own instruments, they use them in performances and in recordings as well. They split the labor evenly - Leon builds the circuits for each instrument, and Brian crafts the consoles that contain them at his home in Catskill, NY. Despite their jetlag from a recent trip to Los Angeles (Brian had screened his film strips at the Museum of Jurassic Technology’s theater), the Dewans gave me a thorough walkthrough of their work, patiently explaining how each of their creations functioned.

Bob Dylan Goes Electronica

This one in via Cole Gaskins

via the Onion

"Audience members at the Newport Rock Festival were 'outraged' Monday when rock icon Bob Dylan followed up such classic hits as 'Like A Rolling Stone' and 'Maggie's Farm' with an electronica set composed of atonal drones, hyperactive drumbeats, and the repeated mechanized lyric 'Dance to the club life!' 'We came here to see the authentic Dylan, the one with the Stratocaster guitar and signature wild blues-rock band behind him," audience member Robert Hochschild said. 'Then he walks out with these puffy headphones, some turntables, and a laptop? The guy's a Judas.'"

Peavey Spectrum Filter Processing A Korg DDD-5 Drum Machine

"This is a Peavey spectrum filter processing a Korg DDD-5 Drum Machine. It is to show what effect it can have on a drum loop. I am mostly scrolling through a couple of different programs and tweeking things.

It features an ADSR Filter Envelope and a ADSR Amplitude envelope as well as the 24db/octave filter and resonance controls. It is processing the drums by the analog trigger level but can also be controlled by MIDI or CV."
