Looking for sludgey-hardcore

I love sludge like the first few Melvin’s albums, the first Eyehategod album, the first Sleep album and Dystopia. I like the tones and the heaviness of sludge but I really don’t like it when sludgey songs are super long. I just can’t into bands like Grief that have 7-9 minute songs. I like it when the music slow and heavy but the songs don’t overstay their welcome either.
