UMUR "Scream Forth Blasphemies" is a demo recording by US, Florida based death metal act Morbid Angel. The demo was released in 1986 and features four tracks which Morbid Angel had worked on and played live for a couple of years. "Scream Forth Blasphemies" features rehearsal/demo versions of tracks which would be included on "Abominations of Desolation" (the band´s shelved 1986 debut album). This would be the last release to feature drummer/lead vocalist and founding member Mike Browning.

"Scream Forth Blasphemies" opens with "Chapel of Ghouls" which is not a professional studio demo recording, but rather a live in the studio/rehearsal sounding track. The sound changes drastically with "Unholy Blasphemies" though, which features a better sounding production quality. Brownings vocals are also more deep death metal growling on "Unholy Blasphemies" than the higher pitched screaming vocals on "Chapel of Ghouls". We´re back to a less polished sound production on "Abominations" and the higher pitched snarling vocals return. The closing track on the demo is "Hellspawn". A noisy, raw, and fast-paced track.

"Scream Forth Blasphemies" should probably be considered Morbid Angel´s first demo recorded in a studio, although it still has a rehearsal tape quality to it. The two previous demo recordings were both raw and primitive amateur recordings, and while these tracks aren´t exactly professional studio demo quality recordings, this demo does a much better job spreading the message that Morbid Angel has arrived. A 2.5 - 3 star (55%) rating is warranted.
