Mark Ronson is one of the formidable DJs and record producers working today. In 2015, his album “Uptown Special” -– which featured collaborations with everyone from Stevie Wonder to acclaimed novelist Michael Chabon -– had gone platinum. It had spawned the inescapable “Uptown Funk”, which won two Grammys – including Record Of The Year – and spent 14 weeks at the top of the U.S. chart and became one of the best-selling singles of all time: 20 million copies and counting. He has also appeared in “Amy”, an Oscar-winning, unflinching film about his late friend and collaborator Amy Winehouse, which became the highest-grossing British documentary of all time. He produced Queens Of The Stone Age’s critically-lauded 2017 album “Villains”, and worked on Lady Gaga’s “Joanne”, an album which went on to have a similar influence on pop as his work on Winehouse’s epochal “Back To Black” — echoes of its stripped-back sound could be heard on subsequent releases by everyone from Kesha and Miley Cyrus to Justin Timberlake and Kylie Minogue. Midway through the sessions for “Joanne”, Mark and Lady Gaga paused to begin work on “Shallow”, a song for the soundtrack of Gaga’s forthcoming film “A Star Is Born”. “Shallow” went platinum in 11 countries and won both a Golden Globe and an Oscar for Best Original Song.
