The Quantum Enigma

After taking a break from the road due to the pregnancy of lead singer Simone Simons and the release of a new concert DVD, Retrospect the band started writing and recording of their sixth album.[9] The album was produced by former After Forever keyboard player Joost van den Broek, recorded at Sandlane Recording Facilities in The Netherlands and mixed by Jacob Hansen.[10] Simons went into the studio, when her son, Vincent, was only eight weeks old. "It was quite stressful for me. I was still breastfeeding, so I was mentally and physically exhausted, like the walking dead pretty much. And singing is very physically demanding. I had a strong schedule of ten days, every day for a couple of hours. We had a very regular schedule together with Joost [van den Broek, producer] and it was super-efficient. I was breast feeding and eating at the same time. Isaac, my mum and my husband would take turns in taking care of Vincent" explained Simons and added: "Of course, I write half the lyrics, Mark [Jansen] writes half the lyrics, and we have to know what we are writing about in order to get into that role, but we’ve been working together for so long so we kind of get each other’s brains, and a big change for me has been pregnancy; it transformed my voice, gave it more dimension. It has a new emotion that wasn’t there before."[11]

In an interview with LiveReviewer, Epica guitarist Isaac Delahaye stated about the making of The Quantum Enigma: "It was very much our intention to really make songs. It was because we started with putting a lot of effort into the basics and we gave a lot of attention to the band part, more so than before. And, of course, Jacob Hansen mixed it and he knows how to do these things. We tried out several people and had them do a test mix of certain songs and he came out on top. It's become a heavy album, yet all the details are there. Previously, we used to go to the studio, tune our stuff and then we recorded an album. This time we did a long pre-production in the studio and we got to check out a lot of different combinations of amps and then we could record it. Previously, we just did everything in our home studios and sent each other the parts. And after that we would go into the studio and that's it. But now we sat down together and discussed a lot more, it was more of a band effort. It was working together, rather than reacting. Everyone brought songs to the table, which was very cool. With the previous album, it was mostly Mark, Coen and me writing a lot. And now even Ariën joined in and that made it all feel refreshing. It's odd to say, but it's kind of a new beginning."[12]

Guitarist/vocalist Mark Jansen explains: "I have been listening to our new album and I can't get enough of it! It sounds more modern, but with all typical Epica elements inside. Refreshing might be the right word. This album has also been the result of a real group effort. It was great to see everyone being so motivated to create our best album! Even though the sound is more heavy (the guitars, bass and drums sound so brutal!!!), it's still a very catchy album as well. Some old influences from our earliest work, some references to Design Your Universe and some new elements."[9] The band further commented: "Where Retrospect reflected on the first decade of our career, we’d like to think The Quantum Enigma marks the beginning of a new era, where Epica sounds heavy, modern and without compromises! Every detail finds its way into a perfectly balanced mix, and makes Epica sound raw and overwhelming."[10]

In an interview lead vocalist Simone Simons explained the main inspiration behind the album: "Well in quantum physics they have done this experiment and they found out that whenever you observe particles they take a certain shape – and when you are looking away, it’s a different shape – so in a way you can say you never know: ‘What is reality?’ We determine our reality through our observations, and if we would look away, reality would change. So the quest of finding out what is reality, what are illusions, is a topic that goes through all of the lyrics – life and death and everything in between. The power of the human mind has been the main source of inspiration for this record."[11]

The album's cover artwork is done by Stefan Heilemann, who also did the cover artwork for the band's fourth and fifth albums and was designed to accompany the ideas behind the lyrics.[10][13]

On 17 March 2014, "The Essence of Silence" was released as a single and was made available for a digital download from iTunes, Amazon, Spotify, Deezer and other platforms.[14] Three days later a lyric video was released on Epica's YouTube account.[15] "Unchain Utopia" became the second single released on 4 April. In an interview with the webzine Sonic Cathedral, Simons confirmed that a video for "Unchain Utopia" was set to be released soon.[16] However, a lyric video was released instead, which features footage originally filmed for the music video.[17] On 30 October 2014 Epica premiered a new video for the track "Victims of Contingency". The video is directed by Remko Tielemans and produced by the Kunststoff Kollectiv, the same team responsible for Epica's highly acclaimed music video "Storm the Sorrow" from their previous album Requiem for the Indifferent.[18]

Simons and Delahaye premiered songs from the new album in an acoustic set at Vintage Vinyl, Fords, New Jersey on 7 April.[19] The whole band reunited on stage on 30 April for an album release performance at 013 in Tilburg, The Netherlands, the first venue of The Quantum Enigma Tour.[20] They went on tour through Europe, Asia, Africa and both South and North America and played 123 shows.[21] On 3 June 2015 Epica announced the last venue for their tour in support of The Quantum Enigma to be 22 November 2015 at Klokgebouw in Eindhoven, the Netherlands and revealed that it was a part of the first edition of their very own festival Epic Metal Fest.[22]

The album was released in five different versions: Regular Jewel Case, 2-CD Digipack, 3-CD Earbook, Double Vinyl and as a digital download.[10]
