This duet, about Lakme and her servant Mallika gathering lotus flowers at the river, is one of the most popular in all of opera. The version that I played this morning features soprano Natalie Dessay
and Delphine Haidan.
Here's a video featuring both Dessay and Haidan.
Here's a link to an npr story from May of 2007 about the "Flower Duet" from the opera "Lakme" by composer Leo Delibes.
