In 1990, Kreyson recorded their debut album Anděl na útěku (Angel on the run) in a studio in Hanover with producer Jan Němec.

Upon the success of Kreyson's first album, Ladislav Křížek released his first solo record, titled Zlatej chlapec (Golden boy), in 1991.

The band played a pre-launch show on 17 March 2007, which was broadcast live on Czech television from Ostrava's ČEZ Aréna, during which they were joined on stage by Germany's Doro Pesch.

With help from sponsors, Kreyson got the opportunity to continue the recording abroad, and they set out for Andy LaRocque's (King Diamond) studio in Varberg, Sweden in 2013.

The entire album was thus recorded in LaRocque's Sonic Train Studios, and the artwork for it was done by famed English illustrator Mark Wilkinson (Marillion, Fish, Judas Priest, Iron Maiden).

[citation needed] In 2016, Kreyson founding member and former guitarist Daniel Krob reached out to a few of his previous bandmates with the idea of a tour commemorating 25 years since the release of the band's debut album Anděl na útěku.

The ensemble, going by the name Kreyson Memorial, began playing shows, and in 2019 they released their first album, a set of original tracks titled Strážci plamenů (Guardians of the flames).

The band was further fleshed out by Michal Kůs (Eagleheart) on guitar and Jiří "George" Rain (Citron, Sebastien) on bass.
