Greg Ladanyi (July 6, 1952 – September 29, 2009) was an American record producer and recording engineer of Hungarian descent, known for his work with many musicians, including Jackson Browne, Warren Zevon, The Church, Caifanes, Anna Vissi, Toto, Fleetwood Mac, Don Henley, and Jeff Healey.
He recounted, "Part of the way I came up into coproducing was by elevating engineering to a point where it has an awful lot to do with the production of the record.
He also co-produced, engineered, and mixed Don Henley's first two solo albums I Can't Stand Still and Building the Perfect Beast.
He co-produced Fleetwood Mac's Greatest Hits (WB), Jeff Healey's "See the Light" (Arista), The Church's "Under the Milky Way" with Waddy Wachtel (Arista), various Japanese artists, Clannad (RCA/BMG), Caifanes, Jaguares, REO Speedwagon (Sony), and Engenheiros do Hawaii (BMG Brazil).
Ladanyi died on September 29, 2009, after falling 13 feet just 15 minutes before Vissi's performance at Nicosia's GSP Stadium, suffering a fractured skull.
