OLDMOON begins to take shape with the exclusion of some very slow songs from INCARNO's 2005 demo. These songs were not released because they were slower than traditional Death Metal and were hidden for a few years. in 2010 a single song named "Deep Death Doom" was published under the name of the extinct band INCARNO, but it is here when the real depressive agony and musical heaviness of OLDMOON begins. Then in 2014 three songs were composed but the sound did not fill the expectations, so that demo never saw the light. One of the songs on that demo was called "Disbelieve" and it gave its name to the first album in 2015. After composing and publishing numerous material in four Splits with some depressive Black and Doom Death Metal bands as Montibus (Argentine), Wintaar (Russia), Stromptha (Greeland), Toxodeth (Mexico) and Poetry of Chaos (Spain) the second album titled "The Osteomantic Incantation" is released in 2020. This second album includes the two songs from the 2014 demo re-recorded with better sound as a previous "Demo tape 2020" and a bonus track unpublished.
