Art review: portraits get abstract
Howard Hodgkin died just before this exhibition opened, so it acts as a fitting tribute to his varied career. Abstract portraiture seems like an oxymoron and many of these paintings are not obviously portraits, with bold colours that are so bright they leap off the canvas and often spread onto the frames.
The artist's aunt's head is not visible at the edges of the painting, leaving us to guess what she looks like — it sums up many of the paintings on display here and their sense of mystery. After a while the show does feel a little same-y but that doesn't detract from the brilliance of many of Hodgkin's works. Howard Hodgkin: Absent Friends at National Portrait Gallery, until 18 June, £12 ★★★★☆ (open every day) Tabish Khan

Theatre review: Puccini turns pain into poetry
The flower and willow world of 19th century Japan is corrupted by star-spangled selfishness in Puccini's celebrated tragedy. Waltzing effortlessly between seductive and sardonic, Marcelo Puente is easy on the ear (and eye) as the callous American lieutenant who marries and quickly abandons his novelty child bride, and Ermonela Jaho is mesmerisingly masterful as the fatally wronged Butterfly. Although a touch sedate at times, the production is exquisitely sung against a backdrop which reflects the shifting mood with a painterly presence. Madama Butterfly, Royal Opera House, Bow Street, WC2E, £31-190, 27 March-25 April, ★★★★☆ Holli-Mae Johnson
Saturday 1 April
