Madonna Bringing the Vibes to Nile Rodgers' Roller Disco Event

Music legend Nile Rodgers is giddy talking about his roller disco event, which is truly on a roll 'cause Madonna's playing host for his grand opening event.

The Rock & Roll Hall of Fame inductee joined "TMZ Live" Wednesday and told us about the awesome vibes going down at his new roller skating palace just outside L.A., dubbed the DiscOasis. Nile's described it as a theatrical journey, uniting "art, light, disco, dance, live performance, roller skating and good times."

So, yeah ... the experience has something for everyone, and it's a beautiful outdoor setting in the South Coast Botanic Garden of Palos Verdes Estates.

Nile, co-founder of the iconic band Chic, will serve as a "Groovemaster" ... and he says Madonna -- along with music mogul Jimmy Iovine and his wife, actress Liberty Ross -- will host the shindig tonight.

Don't roller skate? No problem! Nile says the 10,000-square-foot, outdoor space also offers a dance floor.

Now, he wouldn't spill the beans on whether Madge is gonna slip on a pair of skates, but whoever shows up will also be helping Nile's We Are Family Foundation ... a charity he founded in 2001 to empower youth who are changing the world with innovation.

DiscoOasis is gonna be open at least through Labor Day weekend ... and the Sunday shows include a "Sunset Series" -- with legendary DJs.
