Hearing an album of Bach arias sung by a countertenor may not be essential for every listener. Many of the high arias from Bach's cantatas weren't the kind of operatic pieces that called for a muscular male voice comparable to those that have tackled Handel's arias in similar collections, and Bach, at least much of the time, wrote for female vocalists. If you enjoy countertenor singing, however, this release by Canadian singer Daniel Taylor may be the Bach album of choice. Taylor succeeds precisely because he doesn't try to hit you over the head with acrobatics. His voice is rich, smooth, and lyrical, and it is deployed to maximum effect in music that seems to reflect the almost sensuous approach Bach took to the depiction of religious contentment.
