Alec Baldwin and Matthew Landfield crossed paths one time before their Here's the Thing interview.  In early 2001, Alec was shooting a movie in front of 31 Desbrosses Street in New York's Tribeca neighborhood.  Matthew had grown up in the building in the 1980s, raised by a performance-artist mom and modernist-painter father.  Matthew and Alec said hello as Matthew walked in to visit his parents.  The bohemian scene on the block stuck with Alec over the years -- so much so that when in 2015 he was driving by and noticed that the building was gone, he researched what had happened.  Online, Alec discovered Matthew's labor of love: perhaps the best, most deeply researched article ever written about a single address.  The Lenape, the Dutch, the English, the factory workers, junkies, artists and bankers -- every stage of New York history had some brush with the land (or water) that is now 31 Desbrosses.  Alec was transfixed, and this funny, fascinating conversation is the result.
