The cellist Roger Morelló has intercalated three sarabands from the Suites for Cello Solo by Johann Sebastian Bach. The first is the one included in the Suite No. 1, whose prelude served as primary material for the work by Marc Migó. The second saraband that appears is the one from the Suite No. 2, which is in the key of D minor, and the third is the E flat major saraband. Along with these pieces, we encounter the Suite for Cello Solo by Gaspar Cassadó - a renowned Casals pupil and one of the most legendary violoncellists of the twentieth century as well as a composer. Along with this piece, Morelló has added his cello arrangement of an original work for viola da gamba from Les voix humaines by Marin Marais, which is the piece that lends this album it's title. Side by side with these historical references that have become timeless, Roger Morelló includes two contemporary works. One of them is formed by the Variations on the name of Casals by Marc Migó, a work commissioned by Morelló himself, to whom it is also dedicated. The other contemporary composition that Morelló wanted to include on this album is a work that he commissioned from Elisenda Fábregas, who in turn dedicated it to him. It has Catalan dances as it's title and consists of four dances.
