We love a bit of sibling rivalry. In fact, Noel and Liam Gallagher falling out was probably the most interesting thing the pair of them ever said or did. But, other than a nice juicy rivalry, we love a bit of sibling collaboration as well.
Some of our favourite music comes from siblings who just jell in the recording studio.
Haim, for example, put out what could be considered one of the best albums of 2013. The three sisters are currently owning the sibling thing but there's no forgetting Tegan and Sara and, of course, Mumford and Sons.
Tegan and Sara have been crushing the Canadian twin thing for over a decade and we're still anxiously waiting on their next album with bated breath.
Could the key to having a successful band be to recruit your favourite sibling? That very well may be the case, but don't tell that to Beyonce and Solange Knowles. They rarely work together but they're definitely amongst our favourite siblings.
There is no denying that these things definitely run in the family.
Now is your chance to vote on your favourite power sibling set. Is it Bey and Solange? Haim? Or even the Jackson 5.
