Just to put this discussion in context for future users who might be looking at this, perhaps after some of the screen captures are down...
The url in the original post displays a screen capture of a Google serp display for the official site of the band Coldplay... coldplay.com... showing bullet point listings for Coldplay's concert dates. As the OP correctly points out, most of the data is not available on coldplay.com itself.
As for the sources of the data, you can see both in the screen capture and in a Google search that it's attributed. The Google listings are (currently) showing "More info" beneath each concert date bullet point, both from ticket suppliers as well as from myspace.
I did a Google search for [coldplay] to check current serps, and the suppliers list apparently has evolved, perhaps depending on the events displayed. They currently include viagogo.co.uk, ticketmaster.com, vividseats.com, with individual events listed in myspace.com.
Part of the markup in the myspace listing...
It's a well-structured listing.
If you go, say, to viagogo and use their site search to search for coldplay, in the search suggestions that appear, you'll get a list of dates similar to the Google list but more complete.
It's not yet clear whether Google is at this point licensing these results, or providing them in exchange for traffic, as it did for a while with reviews in places, etc etc etc. Perhaps this is in a testing and evalutation phase.
For movie listings, Google apparently is now licensing its data from various commercial suppliers of such data, who get it from theaters and theater chains...
Where does Google get movie listings?
If anyone's so inclined to search other bands, it would be interesting to see how widespread these bullet points in serps are, and how much they change over time.
Note that bullet point listings and other search refinements come and go on Google, part of what's apparently a continual process of Google's own site optimization, as well as source of data for Google to use in refining its algorithm.
