Here's what Chang had to say via MySpace:
In addition to being a driving force behind the bizarre and bold Human Remains, Procopio repeatedly stepped into Rob Marton's shoes with Discordance Axis, primarily as a live guitarist starting with the Jouhou tours. His only recorded credit with the band is the Necropolitan 7-inch.As we completed work on track 10 of Orphan, it became very obvious we would need a second guitar player to pull off the multi-track compositions that Takafumi had been creating. We tried a few different candidates but finally, one has stuck.
We are happy to share that Steve Procopio has joined GridLink as guitar 2. You might know Steve from his work in Human Remains or seen him on tour with Discordance Axis in 97 and 2001.
On a personal note, it's pretty great working with Steve again, what with our aborted attempt as a grind band, War Chalking, and our years of friendship before/during and after, I am very much looking forward to what Steve has in store for us.
Orphan is shaping up to be a much different record than Amber Gray...just as fast, but a whole new animal. See you at MDF :)
Discordance Axis, Human Remains, and to a lesser extent, Assuck, were pretty incestuous during their existences, swapping in and out members as needed. It seems like Chang is keeping that tradition alive with GridLink as well.
Big, big h/t to Scott for the heads up.
