"This is my gay bestiality song," Luke Sital-Singh says, introducing Luna to a crackle of laughter – an unlikely declaration from a bespectacled young singer-songwriter who comes across as so risk-averse you struggle to picture him smoking a cigarette. A romantic ode to a stranded killer whale he read about in the newspaper, written before he learned said whale was male, Luna is not exactly exhibit A in the case for this sensitive acoustic balladeer being tipped to "do a Ben Howard" – even its author concedes it's "a shit idea for a song". But it evidences the kind of funny levity Sital-Singh brings to his live show, lest the burning sincerity of his music prove a bit much.

Touring a trilogy of accomplished EPs, this native of the south-west London suburbs – just like, hark the omens, John Martyn – promises to mean a great deal to a lot of people. He has been hailed as the British Bon Iver, but his music is pitched squarely at Radios 1 and 2. Think Damien Rice meets Keaton Henson.

Sital-Singh's most impassioned moments sound like the music for American TV drama montages. During Inaudible Sighs, he clutches at the breast of his shirt to emphasise the line "a terrible fear in my chest". Elsewhere, his lyrics find him wanting to "download the sky" and "lose my life to the love I find". It is great if you like that kind of thing, though it does underscore how a more opaquely poetic turn of phrase can unlock a more meaningful truth.

A refined lyrical approach could prove deadly in combination with his supremely confident and controlled voice. Nothing Stays the Same has a ripping, wordless vocal hook crying out to be bellowed by festival masses. Fail for You could erode mountains of cynicism with its heartfelt paean to loving commitment, sung in a trembling tenor that swoops and falls between a whisper and a roar.
