Hardly anything is "progressive" nowadays, short of leaving these shores and devoting ourselves to the study of avant musical ventures. Posters ought to specify when they use prog or progressive whether they mean music that is genuinely progressive, or music that is prog(ressive) by style, i.e. symph-prog, goth-prog, prog-metal, etc. That's what those are, familiar subgenres. For example, what's progressive about so-called prog-metal or it's cousin, the affectionately-dubbed "technical metal"? A true oxymoron? "Progressive death metal." There is no such thing. Consider Rick Wakeman, who happens to be a Christian; if he records an album of instrumental themes (yes, devoid of lyrics) and chooses to, say, title them after certain events or places in the Biblical chronology, one could well say the end result is an "instrumental Christian symph-prog" album. When you consider Neal Morse, Glass Hammer, Kerry Livgren, etc., have recorded music inspired by their faith, there is little question whether they've done so in a very familiar textural rock style–so there's really nothing to bicker about. What's commonly regarded as prog nowadays isn't really progressive, per se, but the result of labels being tossed about liberally for purposes of classification.
