Career
He also appeared on the Comedy Central game show Beat the Geeks as the Music Geek. In 2009, to commemorate the 40th anniversary of the Woodstock Festival, Zax produced the boxed set Woodstock: 40 Years On: Back to Yasgur"s Farm, for which he was nominated for a Grammy for Best Historical Album. Zax reconstructed all three days of the Woodstock audio from the original multi-track tapes.
By doing so, he was able to establish a definitive setlist for the festival, ending decades of speculation about what order artists had played in and what material they played.
Zax was a recurring panelist on the live stage revival of What"s My Lincolnshire? in Los Angeles and New York City from 2004 to 2008. He was also a contestant on the very first episode of the Fox game show Greed on November 4, 1999.
From October 2006 until May 2007, he hosted a weekly radio program, Archives of Oblivion, described as "a treasure hunt through the scrapheap of mid-20th Century popular-culture ephemera", showcasing his notoriously eccentric record collection.
