Return to the Forever saga. The Source is Ayreon’s 2017 double album: Arjen Anthony Lucassen’s biggest, most cinematic sci-fi rock opera yet, and a prequel to the beloved 01011001.

The short version

The 2017 double album by Ayreon, the rock-opera project of Dutch mastermind Arjen Anthony Lucassen, released on Music Theories Recordings. A prequel to 2008’s 01011001, it returns to the sweeping ‘Forever’ science-fiction saga, telling the origin story of an alien race. Across seventeen songs and nearly ninety minutes, Lucassen blends progressive metal, classic prog and symphonic grandeur, voiced by an eleven-strong cast of guest singers drawn from the biggest names in prog and metal. Widely hailed as a return to form, it was one of the most celebrated prog albums of its year.

The origin of the Forever

After exploring the human psyche and other worlds, Arjen Anthony Lucassen returned in 2017 to the sci-fi mythology that had powered some of his best-loved work. The Source, his ninth Ayreon album, is a prequel to 01011001, revealing the origins of the ‘Forever.’ It follows the Alphans, a people forced to flee their home world after it is overrun by their own intelligent machines, escaping aboard a great starship in search of a new beginning — and discovering, on a distant planet, a mysterious source that will change them forever. Lucassen composed and produced the whole epic, played most of the instruments, and once again assembled a remarkable cast, anchored by drummer Ed Warby.

The sound

The Source is widescreen, sci-fi symphonic prog metal, ranging from soaring melodies and orchestral sweep to driving, muscular riffs. As ever, each singer voices a distinct character, and the album unfolds as a series of dramatic exchanges across richly detailed, ever-shifting arrangements. Lucassen draws on classic prog — echoes of Deep Purple, Jethro Tull, King Crimson, Queen and Yes — and fuses it with modern power and progressive metal, all wrapped in cinematic production. More song-focused and immediate than some of his epics, yet no less ambitious, it is a rock opera built for maximum scale and drama.

The songs

The album opens with the towering ‘The Day That the World Breaks Down,’ a twelve-minute epic that gathers nearly the entire cast and is often named among the finest songs Lucassen has ever written. The propulsive ‘Star of Sirrah’ became one of the album’s signature singles, all soaring vocals and driving momentum, while ‘Journey to Forever’ carries the story toward its resolution with sweeping, anthemic grandeur. Across both discs, the interplay of voices keeps the saga vivid and propulsive.

Reception and legacy

The Source was greeted as a triumphant return to form, praised for its melodies, its cast and its cinematic ambition, and ranked among the best prog albums of 2017. For many fans it stood alongside 01011001 and Into the Electric Castle as prime Ayreon, proving Lucassen’s storytelling powers undimmed. Its release coincided with a rare live celebration of the project, The Ayreon Universe, whose limited shows sold out almost instantly. The album cemented Ayreon’s place as the definitive modern rock-opera project.

The verdict

The Source is Ayreon at their most epic and accessible: a sweeping, guest-packed sci-fi rock opera that fuses classic prog, symphonic grandeur and modern metal into one cinematic whole. Come for the monumental ‘The Day That the World Breaks Down’ and the soaring ‘Star of Sirrah.’ As the prequel to 01011001, it is the perfect companion to that album — and, with Into the Electric Castle and The Human Equation, another essential chapter in one of modern prog’s great catalogues.
