UMUR "Yuk Fou" is the second demo release by US, Buffalo, New York based thrash metal act Beyond Death. The demo was independently released on cassette tape in 1988. The six tracks on the 23:39 minutes long demo were recorded live at the River Rock Cafe in Buffalo, New York in 1988. This was the last Beyond Death release to feature bassist Alex Webster and guitarist Jack Owen before they left and formed Cannibal Corpse along with three members of contemporary Buffalo thrash metal act Tirant Sin. Beyond Death folded a year later, but was revived again (without Webster and Owen) releasing a 1990 and a 1991 demo before disbanding.

Despite being a live demo recording from 1988 "Yuk Fou" is pretty well produced perfectly capturing the aggressive and well played live show, which also features some nice interplay with the audience who are also suitably active. It´s funny to hear instructions from the band to the audience that they will be thrown out of the club if they stage dive. It´s obvious Beyond Death had developed their sound and their skills since the release of their relatively immature first demo, and the fact that this was recorded live only adds to the authenticity and power of the release (video material exists from this show and it´s pretty great should you come across it). A 3 star (60%) rating is warranted.
