Google introduced the band Info box quite a while ago as part of the Knowledge Graph, but now if you click on one of the songs you'll be taken to a new page featuring all the band songs in sort of a timeline view (even though it doesn't seem to be sorted by date).
At the moment though, you're not able to listen to the song on Google's Search page itself – when you click on the video thumbnail you'll be transferred to Youtube. It would be cool if it was possible to listen the songs directly from Google search (i.e. via an embedded player), but perhaps that will happen in the future.
To get to the new search page search for a band:
Click on on of the songs on the band's info box:
