The Spanish based oboe quartet, Cuarteto Emispherio - Sarah Roper (oboe) Vladimir Dmitrienco (violin) Jerome Ireland (viola) Gretchen Talbot (cello) - advocates to promote new compositions and already existing works such as the renowned oboe quartets by W.A Mozart and Benjamin Britten. The oboe quartet was formed in 2005 in Seville, where the four members are colleagues in the Real Orquesta Sinfónica de Sevilla.
