Called at the time "avant-garde", but which could now be called "prog-thrash", INTO THE PANDEMONIUM is arguably one of the bravest and best thrash/speed albums of the formative 80s.
Following on from TO MEGA THERION (again, a great progressive speed/thrash album), and the earlier and more primitive (yet still creative beyond what many of that period could even dream of!) MORBID TALES/EMPEROR'S RETURN, this was to prove a watershed for CF. Later albums were poor. Follow-up Cold Lake was rightly universally panned and Vanity/Nemesis was OK, but not great.
Standard (for CF, anyway) heavy tracks like INNER SANCTUM and BABYLON FELL, jossle with a proto-thrash rap (ONE IN THEIR PRIDE), mixed with semi-classical (.. LA LUNE) and orchestral doom (REX IRAE). The influence of CF has reached far beyond the usual thrash boundaries, and many modern bands cite the CF touch in their own music.
MONOTHEIST (2007) marked a return to form, but sadly another break up means that it is very unlikely we will ever hear such music again. A sad loss, but at least we have albums like ITP to fall back on. Brilliant!
