Alexander Calder, Joan Miró And Jean Dubuffet will all have their various gouaches, oils, acrylics and drawings on display at the central London space, allowing punters to witness the pieces in a small, intimate location, free from hordes of tourists, flashing iPhones and hefty entrance fees.
This is particularly relevant to Calder, who next year will feature in a retrospective at the Tate. Anyone who attended the recent Matisse show at the Tate Modern will know how packed these big retrospectives can get, so enjoying Calder's work at a place like Opera is not an opportunity to miss.
The American artist is best known for his mobiles, but this show will host the always brilliant - and often unseen - paintings that were usually overshadowed by his sculptures.
Joan Miró and Jean Dubuffet, who feature alongside Calder, were surrealist painters, authors, lithographers, ceramicists and thinkers, who kicked it in Paris with Calder and all the other Modernist stalwarts who would define the art and literary world for decades to come.
This is a rare chance to see this sort of seminal work in such a unique space, so head on down before the 31 October to make sure you don't miss it.
The exhibition runs from the 14 - 31 October at Opera Gallery London, 134 New Bond Street, London W1S 2TF. For more info check out the website.
