I heard this in an Apple commercial a while back, but didn't know the tune .. or the band, or anything. It's Grouplove, which put itself together in New York several years ago. Tongue Tied is from their debut album from 2011.

Dot Dot Dot is Morse code for the letter 'S,' the full message Guglielmo Marconi claimed to have received atop Signal Hill in St. John's in 1901. It ushered in the age of telecommunications. My maternal grandfather worked as a telegraph operator for Canadian Marconi on Signal Hill for many years.
As well, I have a habit of overusing the ellipsis when I write ... as frequent readers might notice.
