Pink Floyd frontman Roger Walters takes a solo stroll in the park in New York City

Legendary rocker Roger Waters stepped out for a solo stroll on Wednesday afternoon in New York City.

The 77-year-old Pink Floyd singer was spotted taking a walk in the park and later relaxing during a subway ride.

He was also seen wearing a ‘Free Donzinger’ mask, continuing his crusade to free Steven Donzinger, a former attorney who won an $8.6 billion judgment against Chevron before the oil company sued him for racketeering.

He also wore black pants and black boots as he walked through the park, with a Free Donziger mask covering his mouth and nose.

He was later seen relaxing during a subway ride, leaning against a railing as he sat by himself on the train.

Waters is no stranger to activism over his storied career, but over the past few years he has been throwing his support behind Steven Donzinger.

Donzinger scored a shocking legal victory in 2011 when he defended Ecuadorian plaintiffs and scored an $8.6 billion judgment against Chevron.

Donzinger has been under house arrest for the past few years, while he awaits trial, which over 29 Nobel laureates have described as ‘judicial harassment’ against Donzinger from Chevon.

Rally: Waters has even covered some of Donzinger's legal fees throughout the years, and most recently was part of a rally for the former attorney on Monday in New York City

The 36-date tour is scheduled to head through major cities such as Toronto, Chicago, Atlanta, Nashville, Denver and Los Angeles, closing October 8, 2022, at American Airlines Center in Dallas.

‘This Is Not a Drill is a groundbreaking new rock and roll/cinematic extravaganza, performed in the round, it is a stunning indictment of the corporate dystopia in which we all struggle to survive, and a call to action to love, protect and share our precious and precarious planet home,’ Waters said in a statement.

‘The show includes a dozen great songs from Pink Floyd’s Golden Era alongside several new ones, words and music, same writer, same heart, same soul, same man. Could be his last hurrah. Wow! My first farewell tour! Don’t miss it. Love R,’ he concluded.
