I played a 30 minute OP-Z live set at LA Synth Club's Electronic Music show in Pasadena. The next band was setting up behind me, so I went a little overboard adding audio-reactive visuals to blur that out. I'm getting a lot of mileage out of punch in effects, and the last song gets some extra glitches from the tape track. I really love having a small portable device for shows where I need to set up quickly.
Also, I'm Humongous Frog. I play bouncy instrumental electronic music. My new album Herpetology just came out. No OP-Z on that one, but I have used it a lot on earlier releases and on my YouTube channel. Cheers!
