As much as I've always enjoyed the tone of bluegrass, I've tended to think that a lot of the bands in that genre more often than not sound very similar. There's not much distinction, I've found. While The Bottlecap Boys are planted firmly in the bluegrass niche - with some added elements of poppy hooks - they certainly distinguish themselves with their impressive musicality, which allows them to pull out all the stops in a delightfully show-offy way. In the lively "Try and Try," for instance, there's a bit of vocal acrobatics where the two lead vocalists seamlessly trade off word for word in a breakneck refrain. Also helping to make the Bottlecap Boys stand out is the wry humor that permeates their songs, even as they shine as tightly crafted melodies.
