Opus 2 & 4: Chamber Sonatas is the third in The Avison Ensemble's celebration of Corelli's chamber music and the fifth album in their critically acclaimed series of recordings with Linn. Released to mark the 300th anniversary of the death of the composer, the ensemble's greatly anticipated series explores the six opera of the eminent Italian's chamber music: the concerti grossi, violin sonatas, chamber sonatas and church sonatas. Popular since their publication, Corelli's two sets of chamber sonatas are a pinnacle of Baroque Italian instrumental music. They demonstrate a superior level of craftsmanship; they are of the highest quality, exquisitely refined and a good example of perfection in music. Corelli's contribution to the history of violin performance was immense: all six of his published collections of instrumental music demonstrate his exceptional skill as a violinist and composer, but it was in his chamber sonatas that he first used what was to be known as the 'Corelli clash'.
