Mgo de Oz are a Spanish folk metal band from Begoa, Madrid formed in mid-1988 by drummer Txus di Fellatio.The band became well known for the strong Celtic feel to their music strengthened through their consistent usage of a violinist and flautist. The name for the band was chosen, according to founding member Txus, because "life is a yellow brick road, on which we walk in the company of others searching for our dreams." On the 26th of October, 2018, the band played a special concert to celebrate their 30th anniversary, playing with a symphony orchestra at the WiZink Center in Madrid.
