Ill try to make it easy for you.
The first two, Orchid and Morningrise. Do you you like Black Metal? These are not but you can definitely hear influence- vocals for instance. From these check out The Twilight is.My Robe, Forest of October, or Apostle in Triumph from Orchid and Nectar, To Bid You Farewell, and Advent from Morningrise(my favorite album by them).
The next one are mor death metally, if you want that: My Arms Your Hearse, Still Life(2nd favorite) Blackwater Park, Deliverance, Ghost Reveries. Id say check out When, The Amen Corner, and Credence from MAYH. Moonlapse Vertigo, The Moor, and Face of Melinda from Still Life. Leper Affinity, The Draper Falls, and Bleak from BWP. Deliverence? Deliverence, A Fair Judgement, Masters Apprentices. Ghost Reveries? Harelquin Forest,Beneath the Mire, Grand Conjuration.
The Others are more Proggy, Damnation? Windowpane, In My Time of Need, Hope Leaves. For Watershed, Burden, Lotus eater,Hex Omega. Then theres Heritage: Famine, I Feel the Dark, devils Orchard.
