Some composers are merely dutiful conductors of their own compositions, beating time and bringing little else to the table. Englishman John Rutter does more than that.
Arms tightly braced at shoulder level, he stabs, sweeps and punctuates the air around him with his baton, a ball of concentrated energy and pent-up enthusiasm for his own music.
Rutter is 72 now and a legend in choral circles: No choral composer of the past century has been nearly as popular and successful.
Conducting the VocalEssence choirs at the Cathedral of St. Paul on Saturday evening, he was in his element.
Rutter's half of the concert began with the Ensemble Singers, the smaller of VocalEssence's two choirs, performing "Musica Dei donum" to the gorgeous flute accompaniment of Michele Frisch.
The main VocalEssence Chorus joined in for "Hymn to the Creator of Light," a piece laced with questioning chromatic harmonies tinglingly projected by the singers.
A pleasing combination of gusto and technical refinement marked the choral contributions in "Feel the Spirit," a set of seven spirituals in Rutter's colorful arrangements.
The renowned mezzo-soprano Marietta Simpson was the soloist and brought a deep, soulful authority to quieter numbers such as "Steal Away" and "Sometimes I Feel Like a Motherless Child."
