The piece entitled "Bach in the Mirror" for violin and piano (organ) is both a meditative and an expressive homage to Johann Sebastian Bach, in which we also find a balance reminiscent of Arvo Pärt together with the drama of the "Fantasia on B-A-C-H by Artur Kapp. According to Uibo, Bach is not merely a composer, but a "higher spirituality" whose message is only revealed on another level. In Uibo's music we do not therefore find Bach's music quoted purely for the sake of quotation; for the composer, Bach is a higher, spiritual model.
The work can be divided into several sections including a "prologue" and an "epilogue." The solo instrument begins "quasi improvisata" on a long d which immediately becomes a rapid, internally active, arpeggiated D-minor sound area. The beginning tone is followed by two and later three; these represent the Father, Son and Holy Spirit. As a contrast to this, according to the composer, the fast passages symbolise man's nervous, restless activity.
This rhapsodic work, also existing in a version for violoncello and piano, is freely flowing music. Its sonic power and expressive solo part at times call forth very dramatic emotions. The cello's cadenza, or free improvisation opening the final third of the piece, is reminiscent of solo partitas and fantasias in the style of Bach's time. The work concludes with an "epilogue" in which the same elements are used as in the "prologue;" in the end we hear only a low d, also the tonic of the minor key dominating the entire work.
