The late Hollywood icon provided his voice on the band's 'Fire Coming Out Of The Monkey's Head' on their second album Demon Days in 2005.
Singer Damon Albarn told The Sun: "I think he'd be happy with what we've planned. I know he would want to be doing this if he was still with us.
"I saw him three weeks before he passed away and, obviously, he was incredibly ill. But he was very positive about everything. It's important for us to have him there because I know he'd have been there if he hadn't been ill."
Bandmate Jamie Hewlett added: "It's important for someone like him to be remembered, because there will be people in the audience who might not even know who Dennis Hopper is.
"As soon as you show him as Billy Boy in Easy Rider they will know instantly. We've got the song that Damon's going to play, then we felt that in that environment you need to see iconic images of him on screen, so in the short space of time we've had we've been trying to sort it.
"We've got complete clearance on Easy Rider, Sony have been amazing and said, 'Use whatever you want'. It's a perfect environment to do a tribute to Dennis Hopper."
