Frieze week marks the biggest three days of the art-world calendar and brings together hundreds of artists within the boundaries of Regent’s Park and without. Here are five of the must-see shows at 2019’s London event, including Carolina Mazzolari: Emotional Fields at Tristan Hoare. Complementing the Woven section of Frieze London, her exquisite, thought-provoking textiles are made in collaboration with Fine Cell Work.
