Number 57 in my series of beats with that adult swim feel. Light up for this one, seems to be meant for instrumental play. The whole 'marathon' beat concept is essentially a long song either rearranging the sample or/and adding plenty of extra stuff in so that it sounds pretty much like a brand new song.
Sample is Tiny Town from Kirby Canvas Curse
Please contact me if you would like to use this in a project. We can discuss the details.
