We have just blogged here about the Ralph Lauren Art Stars Project and have just found a link via Matt Small to  this Vimeo channel featuring a number of the invited artist's working and talking about their star piece in their studios. Above is the Matt Small video and we have also included French street artist L'Atlas' video below.
Other videos on the channel include one from Pam Glew and another from Harvest & Hannibal. We imagine more will be added in the coming weeks so we advise you bookmark the Art Stars Channel.
