Any K-pop fans out there from the last, last decade? If you are, then F.CUZ and DMTN/Dalmatian should be very familiar names. The groups debuted in 2010 and 2009, respectively. And are from a time in K-pop that feels so distant now.
Thankfully, both groups just released fresh music and I will definitely recommend listening to both. (And definitely check out the rest of their discography as well!)
