Henryk Górecki was a remarkable talent. The Polish composer and champion of contemporary classical music was a leading figure in his country’s avant-garde scene through the '50s and '60s. Total Immersion promises a day-long celebration of everything that made Górecki great. From film and discussion to concerts of his majestic music, there’s a lot to love at the Barbican’s tribute to the late, great composer. Not suitable for under 8s.
