In the past, Anneke van Giersbergen, former singer of The Gathering and mastermind of the Agua De Annique, featured on two Ayreon's albums: Into The Electric Castle and 01011001. The Gentle Storm is one of the many side projects of the Dutch multi-instrumentist Arjen Anthony Lucassen. Officially they are the only two band members, but in their first release they feature Ed Warby at drums, who was also in Into The Electric Castle and Johan Van Stratum (Stream Of Passion) at bass. The album is actually offered in two contrasting interpretations in the one package, a "Gentle" version that presents the pieces in a prettier and frequently orchestrated format, and a "Storm" version of the same core tracks that adds the heavier rock guitars perhaps more associated with Lucassen.
Film composer Eleni Karaindou was born in the Greek mountain village of Teichio and raised in Athens, going on to study piano and music theory at the Hellenikon Odion. Relocating to Paris in 1969, she studied ethnomusicology for five years before returning to Greece to found the Laboratory for Traditional Instruments at the ORA Cultural Centre. Karaindrou's most successful collaboration was with filmmaker Theo Angelopoulos, with whom she first teamed in 1982, going on to score features including 1991's The Suspended Step of the Stork, 1995's Ulysses' Gaze, and 1998's Palme d'Or-winning Eternity and a Day.
