MEDIUM was formed in Santa Clara, Cuba in May 1990 under the name of Cronos, forming the most brutal and extreme death/ grind band in Cuba, all sprang out of Eric Domenech's (vocalist) idea. In June 1991 they released the debut demo ``Epilogo Fúnebre`` containing 6 songs and intro of ultra speed and heavy death/grind which got an excellent response from the critics in spite of its poor promotion.
The band last demo `` God's Perdition`` was released in September 1993 with a palpable improvement marked by an evolution toward techno / death / grind made up of smart and bizarre tones. While this demo won excellent critiques in reknowned magazines like Final Holocaust, Terrorizer and MorticiaNumskull, there was selected together with two others to record the split 7`` Ep ``La Luchas de la Juventud`` through the French label Tiam An Men 89 Recs. Being this the first time a Cuban band appears in this kind of format. It's also found in compilation like ``Circle of Pain`` and `` Massacre from the Jungle``, the latter by a Mexican company, American Line Prods., that would give MEDIUM a record contract. Therefore a large part of 1996/97 was devoted to the preparation of a material containing 8 tracks full of imagination and creativity of extreme, heavy, and tough death metal wrapped in melody, dark, industrial and orchestral effects with musicians from prestigious non metal bands as session guests.
