In The Big Lebowski, after The Dude leaves Jackie Treehorn's, there's a short scene of him running down the street before being picked up by the Malibu police.
A song plays here with heavy drums and a strong bass line, with a psychedelic-rock kind of sound when he is chased by the Nihilists with giant scissors. The song then fades out as we see The Dude at the police station, singing the lyrics to "Branded."
You can see the right moment here.
What is this song? Is it something original from Carter Burwell (the composer on the film) or a popular song? I'm not talking about The First Edition's I Just Dropped In (To See What Condition My Condition Was In) but the short song just after.
