First Inversion begins its fourth concert season this Friday and Sunday with masses by two rather obscure French organist-composers, Louis Vierne and Jean Langlais. Led by founding Artistic Director Lee Wright, the 26-member vocal ensemble presents its "Parisian Masses," featuring two organs. Whether you're an aficionado of sacred music or you just enjoy the human voice, these majestic, uplifting compositions — with Vierne's rich, more traditional take, and Langlais's enigmatic but lyrical modernism — this is a program worth hearing.
First Inversion will perform Friday, January 26, at 7:30 p.m., and Sunday, January 28, at 4 p.m. Downtown United First Presbyterian Church, 121 North Fitzhugh Street. $20 general; $5 students. 520-2003; firstinversion.org.
