OK well you’re not missing much then, cus there’s only 3 albums. The Power To Believe is genuinely pretty great imo. Construkction of Light is kind of a mess and Thrak is fine.
Edit: oh and A Scarcity Of Miracles should probably count as a KC album too. It’s also pretty good. and quite different to anything the band had done before, which is I suppose why it was released as a “a King Crimson ProjeKct”.

Cardiacs friggin rule mate. Yeah “Sing To God” is a tough listen, but “A Little Man And A House And The Whole World Window” is more accessible than you think it is.
