The most impressive recent recording is undoubtedly ‘Codex Calixtinus’ (no. 1 in the list below), a boxed set of four discs that presents virtually the complete music of the manuscript entitled ‘Jacobus’, still preserved at the cathedral of Santiago de Compostela. To be sure, though it has not drawn any comment in this department, the twenty polyphonic pieces that form the appendix to this collection of music have been recorded complete in recent years (Sequentia and Ensemble Venance Fortunat have each devoted a disc to the collection), and the fourth disc of this set duplicates them. Some of these pieces have long been known on records, for they rank with the St Martial sources as the most important examples of polyphony before the Notre Dame period.
