When do the benefits of a bardic perfformance end?

So, when a bardic performance and when to the benefits end? Do the benefits immediately end, or do the effects finish out the round?

I will give a specific example that is the seed for my question. I have a skald with the race power guarded life. If he gets knocked unconscious his raging song immediately ends, so does he benefit from guarded life in this case (ie the song's benefits finish the round) or not (ie the benefits immediately end when the song ends)?

"A raging song cannot be disrupted, but it ends immediately if the skald is killed, paralyzed, stunned, knocked unconscious, or otherwise prevented from taking a free action each round to maintain it."

However, guarded life seems to act before this.

"Benefit: While raging, if the barbarian is reduced below 0 hit points, 1 hit point of lethal damage per barbarian level is converted to nonlethal damage. If the barbarian is at negative hit points due to lethal damage, she immediately stabilizes."

Should be fine.

It’s a barbarian rage power and barbarians have the same issue, so I assume the power just works before the rage or song ends.

Quote:

If a barbarian falls unconscious, her rage immediately ends, placing her in peril of death.

I always viewed that sort of thing as an interrupt to normal flow of operators

Bard singing while at 2HP
gets hit for 10 damage
calculate all modifiers, would include guarded life.
the bard ends up with -4 and 3 temp HP
The Bard is now officially unconscious, so the song stops.
