imperturbably

But this guest-host arrangement is not imperturbably stable, or the end of the story.

The tracks they built rely on imperturbably sustained keyboards, layers of Zsela’s voice in unison and harmony, subdued electronic percussion and myriad near-subliminal sounds.

Cutie continued imperturbably, “And the question that immediately arose was: Just what is the cause of my existence?”

You could say the same of the Queen herself, still looking imperturbably shiny even as the duke drives off to yet another raucous lunch with his ghastly pals.

Ms. Smith, sporting her signature page-boy haircut, brought an imperturbably blithe spirit to the festivities, hewing to the melody despite Prima’s efforts to throw her off.
