Apostolos Sideris was born in 1978 in Athens, Greece, where he had his first musical training, playing the classical flute. By the time he was 15 he had switched to the electric bass.
It didn’t take long for him to fall in love with the instrument ,and he was soon playing with various rock bands around Athens. By the time he was 17, his focus was directed towards Jazz music, something that led him to make the move and go to Boston, in order to attend Berklee. During his time at Berklee, he picked up the upright bass and since then it has been his main instrument.
Following his stint in Boston, Apostolos moved to New York and earned his Master’s degree in Performance, while being instructed by bass virtuoso, John Patitucci. Since then he has been freelancing around the States as well as abroad. He has performed with a wide array of musicians ranging from jazz masters such as drummer Clarence Penn, guitarists Lionel Loueke and Rez Abbasi and pianist Leo Genovese, to world music sensations such as composer and oudist Ara Dinkjian, Greek ECM recording artist Savina Yannatou, Syrian vocal master Youssef Khasab and Lebanese composer Ziad Rahbani. In addition to being a performer, he is a devoted composer, writing in many different styles, ranging from Jazz to Middle Eastern and Latin influenced music.
He currently resides in Istanbul Turkey and he has been directing his creative energy mainly toward working with an Ethnic-Jazz group he co-founded, called MESEL, as well as preparing his own album called ‘?ummation’, which will consist of his own compositions and improvisations, based on Greek and Middle Eastern themes through his own Jazz-influenced perspective.
