In this week's edition of the ArtTactic Podcast, we chat with Ronnie Pirovino, contemporary art collector, curator, appraiser and recognized as one of the early and most prolific collectors of KAWS' work and Lindsay Griffith, Head of Department for Prints & Multiples in New York at Christie's about the intersection between urban art and contemporary art as well as their co-curated upcoming auction Trespassing. First, Ronnie tells us about his collecting background and how he became one of the most widely recognized collectors of KAWS' work. Then, Lindsay, explains why it is the right time for Christie's to embrace the urban art collecting category with this sale with Ronnie. Also, Ronnie discusses the significant number of urban art collectors who have expanded their collecting interests to these more mainstream contemporary artists and why this evolution is occurring now. Further, Lindsay, reveals to what extent her regular clients are showing interest in this collecting category. Finally, they share a few of their favorite works in the sale which occurs from August 5-19.
