The best prog songs of 2015 come from a genre in the middle of a genuine golden age. The modern scene had never been healthier — a former front-runner delivering a career landmark, a generation of younger bands hitting their stride, and the English pastoral revival quietly producing some of its warmest work. Ambitious, emotionally direct and endlessly varied, these are the pieces that show just how deep the modern movement had grown. If anyone still doubted that prog belonged to the present as much as the past, 2015 was the year that put the argument to rest.

Ancestral — Steven Wilson (2015)

The dark, thirteen-and-a-half-minute centrepiece of Steven Wilson’s Hand. Cannot. Erase. (2015), this piece builds from brooding calm into one of the most crushing climaxes of his solo career, guest female vocals and a full string section swelling around it. It anchors a concept album widely hailed as his masterpiece. The Guardian called the record a smart, soulful and immersive work of art, and this is its towering emotional peak.

Towards the Blue Horizon — Riverside (2015)

A highlight of Riverside’s Love, Fear and the Time Machine (2015), this eight-minute piece finds the Polish band at their most spacious and melodic, trading heaviness for a warm, patient build that unfolds toward a soaring release. It marked a softer, more reflective turn that many fans hold among their finest. Few bands balance atmosphere and momentum with such assurance.

The Price — Leprous (2015)

The arresting opener of Leprous’s The Congregation (2015), this five-minute piece announces the Norwegian band’s angular, rhythmically daring take on progressive metal, built on stuttering grooves and a soaring, elastic vocal. It became one of their signature songs and a live favourite, its restless energy setting the template for a run of acclaimed albums to come. Its jittery intensity captured a band pushing the genre somewhere genuinely new, midway between the cerebral and the physical.

Wassail — Big Big Train (2015)

The title track of Big Big Train’s Wassail EP (2015), this near-seven-minute piece distils the English band’s pastoral, story-driven prog into a joyous, brass-lifted anthem rooted in old folk ritual. It became something of a calling card, later reappearing on their acclaimed 2016 album. Warm, melodic and unmistakably English, it captured a band at the height of their powers.

Molok Rising — Gazpacho (2015)

The climactic closing piece of Gazpacho’s concept album Molok (2015), this near-ten-minute track caps one of the Norwegian band’s most ambitious narratives with their trademark hushed, cinematic art-prog, layering delicate texture into a slow, hypnotic swell. Few bands build tension with such restraint. It rewards the patient listener with one of the most atmospheric finales in modern prog.

A golden age in full flow

The year overflowed. Iron Maiden closed The Book of Souls with the eighteen-minute “Empire of the Clouds,” Steve Hackett roamed the globe on the title track of Wolflight, and Between the Buried and Me spun a full prog-metal rock opera on Coma Ecliptic. The Tangent kept the flame of classic symphonic prog burning on A Spark in the Aether — a reminder that in 2015, the genre was firing from every direction at once.
