Bardic Harmony (3.5e Feat)
From D&D Wiki
Bardic Harmony [Epic]
You can combine two types of bardic music to provide the benefits of both
Benefit: You can combine two types of bardic music to provide the benefits of both. Choose two music abilities and activate both (consuming two uses of bardic music) using the same standard action. You can maintain them both by continuing to perform in subsequent rounds, but if either or both require Concentration, you can maintain concentration on only one at a time. The normal stacking rules for bonus types apply.
