Of late, Sam Smith has been adopting an increasingly unrestrained performance style – they dance in a corset, and their bottom is often bared. There were some traditionalists who worried about what might happen at the Proms. But what Smith came up with was a richly soulful night of music – beautiful, and completely in tune with the Proms tradition.

The Royal Albert Hall concert, with the BBC Concert Orchestra, nodded toward Smith's debut album, "In the Lonely Hour," which came out ten years ago. The audience didn't really know what to expect but received an evening of heartfelt and harmless music, which dispelled any kind of worries about unconventional antics.

James Hall, reviewing the performance, said the atmosphere at the event was thrilling, and he himself was surprised at just how conventional Smith's presentation of his material would be. There was a sense of anticipation, he said, before Smith launched into his performance: fans and first-time Prommers were wondering how the whole night would go.

In the end, it was an affirmation of the versatility of this artist who can captivate an audience with their voice and presence without recourse to shock value. This evening paid fitting tribute to their early work and was a memorable addition to this year's Proms.
