Gallery director says collection of 140 paintings will offer a more balanced view of Manchester painter’s work

A new exhibition of work by LS Lowry will “bust a few myths” about the Mancunian artist, who the show’s co-curator says is still wrongly derided for being “naive and uncultured”.

LS Lowry: the Theatre of Life features 140 paintings by the artist, who captured working-class life in the industrial north-west of England during the early and mid 20th century.

Fifteen years ago, Sir Ian McKellen was among the leading arts figures who criticised the Tate for not showing its collection of paintings by LS Lowry in its London galleries and questioned whether the “matchstick men painter” had been sidelined as too northern and provincial.

Now, 50 years after Lowry’s death, McKellen is to star in a BBC documentary that will reveal a trove of previously unheard audio tapes recorded with Lowry in the 1970s during his final four years of life.
