"MishMash" is the creative tandem of artists (husband and wife) – Misha Leykin (born in 1968) and Masha Sumnina (born in 1977).

The name is a combination of the first names of the artists and the English word "mishmash" that means a "mixture", "confusion", and it characterises their creative approach, combining within it an eclecticism of forms, styles and methods. As the artists put it – "In our work we include uncontrollable forces – the wind, mould, water, the viewer etc., exploring the relationship between chaos and order. It's never known which artform they will take – actions, installations, paintings, sculptures, a bread tower or a giant inflatable face".

"Wind Faces" is one of the most memorable works of this art duo, consisting of bedsheets sewn in such a way that the wind can fill them, giving them form and turning them into masks. These objects were exhibited in St. Petersburg as part of MANIFESTA-10, in Tallinn, Brooklyn, and at the entrance to Gorky Park in Moscow.

Leykin and Sumnina show fine art, architecture and design projects. The professional roots and origin of this duo have determined the main features of their joint work: interactivity, working with space (Mikhail is an architect by education) and the influence of Conceptualism (Maria is the daughter of one of the key representatives of Moscow Conceptualism, Andrei Monastyrski).

They are Laureates and Nominees of numerous awards in the field of Contemporary Art: artist of the year Cosmoscow 2019, the Tretyakov Prize (together with Olga Petrunenko) (2018), the Terna Prize (2013), Kandinsky Prize (long list 2007, 2014, 2015, 2016, 2019), Innovation Award (shortlist 2011), competition for the design of the September 11 Memorial in New Jersey (2005).

Their solo exhibitions were held at the Moscow Museum of Modern Art (2016), the Multimedia Art Museum (MMAM) in Moscow (2011), and others. Their works are in the collections of the State Tretyakov Gallery, the NCCA in Moscow, the Moscow Museum of Modern Art, and private collections.
