The Portuguese Chamber Orchestra (OCP) was founded on July 5, 2007, and its debut took place on September 13, 2007, with the opening concert of the 2007/2008 season at the Grand Auditorium of Belém Cultural Center, in Lisbon.

The Belém Cultural Center (CCB) hosted OCP, first as associate orchestra, and since 2008 as orchestra-in-residence.

Their presence at the annual music festival "Music Days in Belém" has been constant, making room for new soloists and conductors such as Pedro Amaral, Pedro Neves, Luís Carvalho, Alberto Roque and Jose Gomes.

OCP has worked with composers Emmanuel Nunes and Sofia Gubaidulina and also played with renowned soloists Jorge Moyano, Cristina Ortiz, Sergio Tiempo, Gary Hoffman, Filipe Pinto-Ribeiro, Carlos Alves, Heinrich Schiff, Antonio Rosado, among others.

Earlier we had heard undeconstructed Chopin: his Second Piano Concerto characterfully played by Cristina Ortiz with the Portuguese Chamber Orchestra.
