Kyuss Lives! say they are "shocked and saddened" by Josh Homme's decision to sue them.
Homme, who now fronts Queens Of The Stone Age, was an original member of Kyuss until their split in 1995. The other three members reunited under the banner Kyuss Lives! in 2010, but this week Homme claimed that they were attempting to steal rights to the original Kyuss name.
At the time, Homme said: "With open arms, we made every attempt to help them continue Kyuss Lives respectfully. Only to discover while they looked us in the eye, Kyuss Lives! management and band had filed federal documents in 2011 in an attempt to steal the name Kyuss.
Now the band have responded (via Spin), and seem disappointed that Homme decided to make the issue public:
"We are both shocked and saddened that our friend and one time band mate has chosen to file a lawsuit against us, especially after having positive discussions since our reformation.
"We look forward to resolving this private matter behind closed doors and moving forward with work on our new album and connecting with our amazing, loyal fans."
While the legal tangle continues, Homme continues work on the forthcoming Queens Of The Stone Age album, due for release later this year.
Does Homme have any right to the name if he refuses to partake in the reunion, or should the current lineup respect the untarnished legacy left by the original Kyuss, which pioneered the stoner rock genre? Tell us what you think in the comments.
