I love Young Fathers - Shame.

Not sure about the rest of their repertoire but this song really is great and worth a listen I think. (Hope it qualifies as 'indie rock'. Apologies if it doesn't!)

Not really new but I've been listening to "SKATERS" for a weeks I think theyre cool
again not really new but "JAWS"s new single is cool. I dont know it kinda seems to me these days there are not really many bands who manage to follow through. usually its one good ep or a half decent album after that you kinda get a forced vibe.

some other newish bands i like : black books, hop along, video age, Harlem

Houndmouth- Sedona

Houndmouth is really good, I love all their stuff but Sedona is a great first one. Katie Toupin, the singer left so i think they still play but ya know, katie was awesome.

If someone uderstand italian language, or at least enjoy hearing italian music, I suggest a rising band called "thegiornalisti". Giornalista is the italian word for journalist.
They are really good with guitars and voice. Good songs to start are
Il tuo maglione mio (that means "your sweater mine" or something like that)
and
Completamente

Indie Rock... have to say Jangly Mark and the benefits from Swansea in the U.K.!

Not sure it's indie rock, probably more dreamish than rock, but have you guys heard of Jay Som? Believe it's an upcoming thing. The music has nice vibes ^-^

Best new indie band for me is Alias Kid, from Manchester
