Nulbarich is J-Pop/Rock group who debuted in 2016. Their name is a portmanteau of "null but rich" (or rather, being satisfied despite having nothing).
The group is led by Jeremy Quartz (JQ) who is the only official member, with no other fixed members of the group. He is inspired by funk, pop, rock, and acid jazz. They made their debut with the single "Hometown" in May 2016, which was followed by the album Guess Who? in August. Despite it being their debut album, it charted for several months on the Oricon charts. The album also spawned a couple of analog EPs.
