Ángel Ontalva is a guitarist and composer with an extended trajectory in creative musics, exploring the boundaries between progressive rock, experimental music, free improvisation, jazz or ethnic music, with an idiosyncratic language developed through decades of intereaction with different musical traditions and endless collaborations with musicians from all cultural and geographical background.

Ángel is also the founder of the discographic label octoberXart Records. 

As a solo guitarist he uses to play his own compositions in an open way with wide space for improvisation, making of each concert an unique experience, always different, often using alternative tunings and extended or unusual techniques for to construct different ambiences and textures, always exploratory but putting emphasis on melody.  

With October Equus, Ángel has participated at the more important european festivals dedicated to progressive rock and creative musics: Rock In Opposition Festival in France, Gouveia Art Rock Festival in Portugal, Freakshow and Zappanale in Germany, MamFest in Madrid or AltrOck Festival in Milan are a few of them.

In October 2018 he organized the first octoberXart Records Festival at the legendary DOM of Moscow.  

Formerly a draughtsman and painter, Ángel worked long time as a freelance animator and illustrator in parallel with music. At some point he decided to focus totally to music and stop his professional activity in the visual field. Years after his retirement, he was offered to make an exhibition in Nizhny Novgorod in 2017. He took this occasion as a comeback and since then he did seven exhibitions in Russia, in wonderful places as for example the Theatre of Opera and Ballet or the Khlebnikov Museum in Astrakhan.
