ill go wild and varied!!
when you say wild a band that comes to mind is midori :D their music definitely sounds wild and frenzied, you should listen to "yukikosan" to see for yourself :3
for a familiar name there's radiohead xD sure it might not sound too wild but the stuff from their 8th album is very interesting, like "bloom" with its confusing drum beats :D
another band that sounds like despair is this heat!! their song "makeshift swahili" is a little nugget of cerebral post-punk that can be a bit unsettling :o
finally a band that has uncommon compositions which still ultimately sound endearing is women, you can hear this in their song "shaking hand" :3
i hope you like any of those!
