What is progressive rock??

[transatlantic]

This music station called Aural-Moon progressive music. Some music i listen on this station isn't progressive rock music. I think you can't call this station progressive

Progressive music: Pink floyd, Yes, Rush ,Dream Theater, IQ, Caravan, Flower Kings, Spock'Beard, Marillion, ELP,transatlantic and genesis.

This music is progressive. It sounds hard, instrumental, solo, and it isn't soft or boring.

That's my meaning about progressive rock
