The ninth edition of Art Dubai opens today and I am happy to report that ‘the most global of art fairs’ lives up to its tagline: this year's programme includes work by more than 500 artists and 92 galleries hailing from more than 40 countries. More galleries than ever are presenting high-concept booths focused on just one or two names, allowing visitors to immerse themselves in the work of individual artists more fully than is usually possible at events as busy (and commercially driven) as this. Here are three galleries at whose booths I couldn’t help but linger.
