Crowded House at the Masonic Hall Grand Lodge in New York. The Artists Den (www.TheArtistsDen.com) has been presenting emerging and established musicians in unique settings around the world since its inception in 2004. Founded by Mark Lieberman, the venture began as one music lover's vision of staging great live music in non-traditional settings, and his desire to share these concerts with friends and fans. Initially a series of intimate living room concerts, The Artists Den has expanded to include concerts across North America and Europe by some of today's most significant names in popular music, in venues as varied as an abandoned warehouse in San Francisco, a cellar stage in Montreal, a private Southampton beach house and the diamond floor of Tiffany's on Fifth Avenue.
