Upon first entering Bird’s Basement, I was immediately conscious of the crystalline sound of the piano, each unamplified note lingering in the space, untrammelled by its neighbours. The audience, in darkness, appeared hushed, as if intensely focused on the music: lyrical, melodic and restrained. As I was drawn into this music, I was conscious of its fragile delicacy, as Mark Isaacs mined the upper register, unafraid of summoning sheer beauty from his instrument.
