Robert Plant

Ex-Led Zeppelin frontman Robert Plant has fired back at his former bandmate Jimmy Page after the guitarist criticized him for being a no-show when the legendary group were honoured at the Grammy Awards earlier this year, ContactMusic.com reports.

Plant, who is getting set to launch a new solo album and tour with his band The Strange Sensation, cited the new project as the reason for not flying to Los Angeles for the award ceremony.

"Jimmy had a bit of a go at me for not being there, but what can you do? What I'm doing now is more important to me," he told ContactMusic.com.

"It's great to look back and smile. But middle-aged self-congratulation is very dangerous."

Led Zeppelin were awarded the Lifetime Achievement Grammy Award on Feb. 12.

Plant will release his new disc "Mighty ReArranger" on May 10.
