Yanni Voices

For the past 25 years, Yanni has had a pretty good thing going, given that his grandiose neo-classical instrumentals and romantic piano ballads have won him an intensely devoted worldwide following. So it’s a surprise to find him messing with the formula, adding a quartet of vocalists to the orchestra on his latest album, “Voices.” Somehow, though, the singers don’t get in the way or dominate the compositions, but rather make the experience even more, um, Yannier. You’ll have to go to Scottrade to see if that holds true in concert. (Daniel Durchholz)
