Balance is such a delicate thing. Finding that elusive equilibrium between musicians so that the whole is greater than the sum of the parts and yet each part can shine in its own time. If it's to happen, egos must be jettisoned and the music must be master.

Osna are a newly-minted quartet from Mayo and even a cursory listen to their eponymous debut reveals a poise and symmetry which suggests a maturity that vastly surpasses their obvious youth.

Osna's sound is dominated by pipes, low whistle, accordion, piano and guitar. Miraculously, they've managed to meld fine vocals intermittently to the mix without displacing the scales.

Whether it's the stripped down air of 'Inis Ge' with just vocals, keyboards and low whistle, or the elaborate pyrotechnics of the 'Hag’s Purse' set, Osna yield to the demands of the music.

Comparisons might be odious at this early stage of their career, but it's difficult not to conjure up thoughts of the magnificent ensemble playing of Solas and Dervish when Osna step centrestage. This makes you yearn for the live set. Surely the ultimate recommendation.
