As previously reported, late Rolling Stones pianist and tour manager Ian Stewart will be honored come April 19 via Boogie for Stu, an 11-track tribute record featuring brand new recordings by PJ Harvey and all four current Stones — Keith Richards, Ronnie Wood, Mick Jagger, and Charlie Watts — that was helmed by pianist Ben Waters. All proceeds for the project, which was mixed by the great producer/recent Ryan Adams collaborator Glyn Johns, will be donated to the British Heart Foundation. A few weeks ahead of the drop date, however, you can get a solid preview of the project via 60-second samples here or the shorter clips below. Standouts so far include PJ Harvey’s take on the Doc Pomus-penned Ray Charles classic “Lonely Avenue,” recorded on Stewart’s piano, and the Stones covering Bob Dylan’s “Watching the River Flow.”
