You might want to listen to MAYTREE . They're a Korean acapella group . They not only sing but replicate the sounds of instruments and electronics . Pentatonix are good but Maytree are on another level .
@@jcs1025 They're both acapella groups . Maytree also sing songs from just about all genres. Pretty sure Maytree are all classical trained opera singers . So they're both acapella, both sing others songs . They can sing every song or genre that Pentatonix do and then some . While there's no doubt both are extremely talented. Pentatonix are famous in the USA and known in other parts . Maytree are famous throughout all of Asia known throughout the world , maybe not America ( 4% of the world's population). And are highly rated as individual singers of classical music. So Pentatonix fan base at its extreme projection would be around 500 000 . While Maytree extreme base would be in the Billions . EDIT sometimes when Maytree ( 3 men and 2 women) perform 3 of them would sing and the other two would make the sounds of the musical instruments. Different members excelled at different songs or sounds . They also do electronic game sounds and themes for movies and games , if you close your eyes you'd never suspect these are human voices . One last piece of information Maytree are the World's biggest and most popular acapella group in the world . Based on ticket sales , record sales , merchandise . Unlike Pentatonix who only outsell them in the US bible areas .
