Wishing for a cornucopia of exhibitions? And from one of the world’s leading galleries? Look no further than Galerie Perrotin’s online platform, which features tours of over sixty past exhibitions from its worldwide outposts. Selections include black paintings by Pierre Soulages, sculptural works by Takashi Murakami, Josh Sperling’s colorful installations, and Chen Fei’s complex vision of the figurative world. The list goes on, and it’s a great way to catch up on contemporary art during an empty afternoon. —E.C.
