charts. At the end of 2007, the band professionally recorded a sold-out show for 8,000 visitors at the Beursgebouw, in The Netherlands, for a possible future DVD release. On 7 February 2008, the band performed a special show accompanied by The Metropole Orchestra, the Pa'dam Choir, and special guests including George Oosthoek (ex-Orphanage), Anneke van Giersbergen and Keith Caputo of Life of Agony, filmed by 14 HD cameras at the Ahoy Arena in Rotterdam, with an attendance of 10.000 people. This recording was later released as the main show of the Black Symphony DVD, and some parts of the show in Eindhoven came as an extra on the second disc of some editions of the album. Both shows featured special stage effects like explosions, pyro and fireworks. Reception The criticism of The Heart of Everything was generally positive, with particular praise for the symphonic elements and Sharon den Adel's vocals. Chad Bowar of About.com praised the use of different elements on the album, while saying that the album has "the optimum balance of the melody and hooks of mainstream rock, the depth and complexity of classical music and the dark edge of gothic metal."

Mark Gromen, from Brave Words & Bloody Knuckles, praised specially the track "Our Solemn Hour" by offering "an accurate portrayal of what Within Temptation are all about, (...) grandiose, orchestral and rocking, it encompasses all aspects of the band."
