‘Dynah & Donalogue’ is, apparently, an old Irish a cappella folk standard. In this demo track of sorts – it was actually recorded live at last year’s Truck festival – Flights Of Helios transform it into a huge, shimmering six minute mass of sound. It opens with a windswept, Ambient-style wave that reminds, both musically and in a chakra-tweaking sixth-sense kind of way, of live Orb recordings from the mid-1990s; all endless echoes of sound and carefully-constructed and effortlessly subtle melodic lines.

Flights Of Helios have at their core Sebastian Reynolds, late of The Evenings, Sexy Breakfast and a million other bands, side projects and one-off experiments. As well as drawing on the delicate, arpeggiated guitar tones of mysterious folk artist Rob St John, and the slightly baleful, yearning vocals of Harry Angel’s Chris Beard, Reynolds assembles a layered soundscape here that provides an organic feel to those which are presumably largely electronic sounds.

As a demo in the most literal sense – a demonstration of what Flights Of Helios are capable of – ‘Dynah & Donalogue’ nails it. Simultaneously warm, sinister and steeped in musicological exploration, it marks the band out as a chilly reflection of the cheekier, sunnier exploits of fellow Oxford artists such as Chad Valley and Wild Swim. It also aligns Flights Of Helios with them in terms of quality and soul, despite their sarcastic self-tagging as ‘grief folk'; a cynicism-free band that’s as unsettling as it is relaxing.
