Founding Pink Floyd, began its rise as one of the most creative and powerful psychedelic bands on the British scene.

In that early period, Wright was a major force in the band's pioneering experimental sound, penning the songs The Great Gig in the Sky and Us and Them on Floyd's legendary 1973 black-light rock opus Dark Side of the Moon.

At their peak, from the early 1970s through the early 1980s, Floyd were one of the most popular, successful and influential rock bands in the world.

Floyd's commercial breakthrough, 1973's Dark Side of the Moon, was their first #1 album in the U.S. and spawned what is likely to be a once-in-a-lifetime chart juggernaut, remaining on the Billboard albums chart for an incredible 741 weeks to date " including 591 consecutive weeks, from 1976 to 1988 " on its way to selling more than 40 million copies worldwide.

However, as the 1970s progressed, Wright, along with Floyd singer/guitarist David Gilmour and Mason, found his contributions diminishing as Waters increasingly dominated the band's songwriting and direction.

In a group whose history is rife with decades-long grudges, Wright was not immune to the inter-band drama, splitting with Floyd in 1979 during sessions for The Wall, due to his strained relationship with Waters. He returned to the group as a paid session musician for shows in 1980 and 1981, but he was not included on 1983's The Final Cut, the only Floyd album on which he didn't appear.

Following Waters' departure, Wright rejoined the band in 1988. He played keyboards and sang on A Momentary Lapse of Reason and co-wrote five songs on 1994's The Division Bell.
Wright, who performed on every Floyd tour, was also onstage in 2005, when the surviving members of the band played a rapturously received reunion gig at the Live 8 concert.
