In reply to Fierce & all -Not here for b****** that can only slay in studios.

"always branded themselves as very talented."

LOL What a shocker, they called themselves talented.

Their harmonies were nothing special, and neither was their acapella. It was simple barbershop quartet harmony with an extra voice. Only two people sang and out of those two, only one was actually a good singer. Justin was and is way too nasal.

Backstreet Boys literally got their recording contract from singing acapella constantly, which they do to this day. They were heavily influenced by Boyz II Men. The casting call for them was "New Kids On The Block look with a Boyz II Men" sound. They were even branded a "white Boyz II Men." Without provocation, they will drop everything and sing acapella on the spot anytime anywhere. They can harmonize at the drop of a hat. BSB has way more complex harmonies, because they utilize vocal polyphony. They are masters at acapella modulations. In one medley, they did seven key changes. They do a lot of vocal stacking and excessive syncopation.

NSYNC are remembered for their dancing and bizarre outfits. They were never known for their vocals. BSB were and are known for their harmonies. That's why NSYNC is only known as a boy band, whereas BSB is always referred to as a vocal harmony group first and foremost, then a boy band.
