Boy,are you in for a treat! I agree that Dear Daddy is a little off,especially for GH. I'm not too fond of the beginning of Salvation Station either. 'IF' is devoid of such weaker moments. It,IMHO,is the greatest prog cd of all time,bar none. I also highly recommend Shadowlands, Lex Rex, and The Culture of Ascent (feat some vocalizing by Jon Anderson and lead vocals by Carl from Salem Hill). 'The Compilations' has some of their best jams on it as well. Previously released on the 3 cd box set ' The Odyssey', the track ' In the Court of Alkinoos' is an EPIC of grand proportions!
The vocals are a bit of an acquired taste but Chronometree is their best early work and also has some INCREDIBLE ELP-demolishing tracks. (Sorry,Keith..I'll help you re-weld your doors back on!)
Their 2 cd set The Inconsolable Secret is brilliant and the band is planning to redo the entire set ,so perhaps you can get a hold of that as well. I have the original,complete with Roger Dean custom artwork and ,although there are a few 'skip' moments,it is a musical milestone as well. To BEGIN to describe the musical edifice that is the 24+ minute 'The Knight of the North' would be ridiculous. Being out of print for a while this one will be a 'must have' even for those of us who have the original! Just stay away from their foray into cyber-rock/folk/pop 'Three Cheers for the Broken Hearted' - very well done but definitely not prog! Live at NEARfest, also out of print, is a good disc to scrounge for as well,far superior to 'Live and Revived. Featuring Rich Williams of Kansas stepping in for GH's rendition of ' Portrait (He Knew)' ,it is a noteworthy live set. Happy listening--you are perhaps the most envied of all men,sir, as you sit perched on the edge of the great chasm that is 'GLASS HAMMER' !!
