Please note the links below, especially for the mp3s.
Two months ago the LCMS held its Model Theological Conference on Worship. While I wasn't there, I enjoyed reading the insights of conference participants via Southern Lutheran Kantor, Fine Tuning, Liturgy, Hymnody, and Pulpit Quarterly Book Review, and Necessary Roughness.
The LCMS Commission on Worship just posted the MP3 files of the conference speakers on their website. While certainly not a substitute for being there, these MP3s do allow for greater distribution and review of the topics. Yet another opportunity for exploration.
