In 1998, David partnered with his friend Ross Power, an internationally recognized metal sculptor, who worked out of a cavernous old warehouse in what was then, the very derelict Miamis Design District. David loved the place, and kept seeing it as more than just a series of artists studios. He envisioned a restaurant, nightclub, cinema, and recording studio, and a cutting edge venue for performance art. The aptly named Power Studios opened to the public in 2000 with the Poets Cafe, a gourmet dining room/art gallery, three performance stages, the IANI 32 Track Digital Recording Studio, and a star light movie theatre on the roof top. Power Studios is now used exclusively for private projects, and a re-opening of the nightclub is planned for 2009. David also takes great pride in his son Joshua, who went from calling the Bingo numbers at The Eastern Sun as a child, to managing the floor in Mangos as it grew into a sensation. Today Joshua is the CEO of his own company, CR Media. David, a partner in CR Media, helped develop a multi year, world-wide deal with The Hertz Corporation and Viacoms Nickelodeon, for the distribution of a Portable Media Player, pre-loaded with 50 hours of Nickelodeon movies and shows, for families renting Hertz vehicles. The Nick on the Go¢ video players are already in 43 airports throughout the United States from coast to coast with international expansion planned throughout the world. In addition, David and Joshua have also partnered in the retail frozen food business with Mangos Tropical Cafe branded Mambo Chicken Wings¢. Mangos wings are now in all South Florida Publix grocery stores from Palm Beach to Key West, as well as in ShopRite and A&P supermarkets in New York, New Jersey, Connecticut and Pennsylvania. David and Joshua Wallack, father and son, continue their enthusiastic legacy of imaginative innovation.
