What Prog do you find the hardest, or, impossible to like?
I enjoy subtlety, unusual time signatures, some complexity and strong melodies. So.....I really have no ears at all for Progessive Metal, Industrial and the like. Bombast doesn't appeal to me at all. Growling vocals tend to make me laugh or cringe, depending on what mood I'm in at the time.
Also, can't appreciate certain elements of the unstructured/all improvised/free jazz prog scene. Now, Coltrane's "My Favorite Things" album is, to my ears, inspired work. The Dave Holland Quintet's "Extended Play: Live at Birdland" isn't; just noise and chaos.
Bands I enjoy the most are Weather Report, Yes, Genesis, Big Big Train, early to mid period Porcupine Tree, Pink Floyd, certain Art Zoyd tracks, certain Sieges Even tracks, the double live Bill Bruford's Earthworks album "Footloose and Fancy Free", certain Birds and Buildings tracks, iamthe morning, Mahavishnu Orchestra, King Crimson, Neal Morse's "?", Penguin Cafe Orchestra, Philp Glass' "Low Symphony", David Bowie, Portugal. The Man, Pure Reason Revolution, Tull, Sia, Steely Dan, Super Furry Animals, TV on the Radio, Underworld and The XX.
