Michael Berkeley’s guest is the artist Heather Phillipson whose giant swirl of cherry-topped, fly-blown whipped cream has recently been installed on the fourth plinth in Trafalgar Square.

Heather was a serious classical musician in her teens, and often uses music she’s composed and performed in her work.

She talks to Michael about music she’s loved since her childhood, including a Mozart symphony and Prokofiev’s Peter and the Wolf; a radical opera by Robert Ashley from the 1980s that has had a profound influence on her work; piano music by Grieg which reminds her of her grandmother; and the soaring emotional impact of Beethoven’s Piano Concerto No 5.
