Beside the above mentioned here's a list of others that might be worthy a search on youtube, but I never listened any of these (to my knowledge, maybe Üveges Csirkeszemek is an exception).
CsizmáSKAndúr
Üveges Csirkeszemek
Macsakanadrág
Burzsoá Nyugdíjasok
A tizedes meg a többiek
C.A.F.B.
ETA
Kretens
QSS
Elit Osztag
Fürgerókalábak
Some of them might not give the wished result when searched tho.

And I forgot one major band: Vágtázó Hallottkémek and it's vocalist Kolozsvári Grandpierre Attila (https://en.wikipedia.org/wiki/Attila_Grandpierre his pops also an interesting person, a historian who rediscovered Tarih-i Üngürüs)
