The use and understanding of language in society and human history is of great interest to socialists and anyone who wants to understand how human society developed. This exhibition by young artist Adam Thomas investigates language and our understanding of it.
Tate Liverpool, until 25 April 2010
The opening pieces in this comprehensive exhibition express its major theme. The artists of the Black American avant-garde of the 1930s were as influenced by the contemporary trends in European art as they were by the vibrancy of the street life and jazz culture of the US ghetto. The artists of what became known as the Harlem Renaissance reacted against the exoticisation of non-European peoples, typical of the "primitivist" art of a previous generation, by embracing the styles current within the world of European art.
Tate Modern; Until 16 May
The transformative impact of the Russian Revolution on art has been the impetus for a series of excellent exhibitions at Tate Modern. Albers and Moholy-Nagy: From the Bauhaus to the New World (2006), Kandinsky: The Path to Abstraction (2006) and Rodchenko and Popova: Defining Constructivism (2009) all drew attention to the imaginative explosion that took place internationally in the wake of 1917, while not always telling us about the social processes that gave birth to such dynamic movements. This exhibition continues in this vein.
Graves Gallery, Sheffield
Robert Mapplethorpe, who died of Aids in 1989, remains one of the most widely known LGBT photographers of the last 40 years. Mapplethorpe made large, stylised black and white photographs of great abstract beauty, including portraits of celebrities, pictures of flowers and male and female nudes.
Magnum Print Room, London
Landscape photography is rarely just a celebration of stunning views and nature's beauty. The genre has often been ideologically loaded.
For example, early images of the US landscape were a celebration of the supposedly empty land being opened up to colonialism. The genre can also be used effectively to highlight the impact of war, development and capitalism on the landscape. Landscape photography has developed along two routes: artistic and documentary. There is often a crossover between the two.
Space, Hackney, until 19 December
Ruth Beale's project is to stage an exhibition of political and literary pamphlets dating from the 1930s until today with some paintings based on them.
It is not just something to look at, although all the pamphlets can be picked up and read. It is a piece of political art designed to provoke discussion on the history of the political intervention that a pamphlet represented and represents, and whether this is still relevant in the internet age.
