Help exploring new acts within the undercard, recommendations please!

I definitely don't recognize barely any acts in the undercard compared to other festival undercards or even previous bumbershoot undercards. I have a feeling they more so went "el cheapo" and didn't get many great undercard acts rather than me just not knowing these hidden gems! haha, maybe im wrong though. But last year for example undercard consisting of ToKiMonsta, St. Lucia, hippie sabotage, jagwar ma, joywave, lewis del mar, even up to kamasi washington, cashmere cat, etc....most people at least recognize all these names. Ive been listening through on spotify and im really just not impressed so far. Havent found really any diamonds in the rough, ive checked out stuff even towards the top like 5th line, like big wild, LANY, highly suspect, amine, watsky was ok...i guess...for someone i would expect on the bottom 3 lines or something, red fang, i dunno not thrilled so far. For someone that likes for example Flume and odesza, and like vince staples and the roots, or going back to last year bands like tame impala or anderson paak, run the jewels. any suggestions in the undercard for good hip hop, electronic, soul, good indie rock?
