Is it karma? Probably not. Is it a bit ying and yang? Maybe. Or perhaps it is just simply poetic that after a month of open letters and debate over how women in the music industry conduct themselves, Warpaint choose another all-female band, PINS, as their support. Now, as a male writer I may be criticised for pointing that out and quite rightly too. It shouldn't matter whether the band on stage is male, female, gay or straight but unfortunately it is hard to escape the fact that the two bands are solely made up of young women when sections of the Brixton Academy crowd still insist on wolf whistling and jeering between songs. This behaviour is about as unavoidable as screeching teenagers at a One Direction concert, it seems.

Grown women on a stage, to some men it would seem, still negates them to be looked upon like 1920s showgirls with the antiquated attitude to match. Neither band are provocative on stage and they aren't naked on wrecking balls or licking sledgehammers in their videos, and there isn't a foam finger in sight. The lyrics in their songs aren't littered with innuendos about disco sticks, they are instead strong and independent, willingly or not the music both bands create says more about the strides women are making within the music industry than all the words that have been written over the past few weeks.

Manchester four-piece, PINS take to the stage with the confident swagger you would expect from a band who have been receiving rave reviews from all quarters and have only just themselves completed their own successful headline tour. This is no more evident than their strong setlist which offered several songs from the band's debut album including the title track, 'Girls Like Us' as well as the incredible 'LuvU4Lyf', sounding so much more powerful live than it ever has on record (this is one of my favourite songs in the past year or so).

Warpaint come to the fray to a rapturous welcome and start with 'Keep It Healthy', a relatively new song taken from their forthcoming self titled, sophomore album. If your band is going to have a drummer and a bassist then they must have a connection beyond the understanding of the human mind; Jenny Lee Lindberg has certainly found that connection with Stella Mozgawa. They form the rhythmic foundation of this band that allows Emily Kokal and Theresa Wayman to play with the freedom and artistry that allows Warpaint to be a truly great live band.

With a back drop of an LED light wall displaying tie-died patterns and blocks of bright colour complementing the moods of the set which weaves its way between old and new songs and both fill the Brixton auditorium with the most pleasant noise one could wish to hear on a chilly October evening when just starting to come down with a bout of a cold. It's almost three years since the LA outfit released their debut and the new material has benefited from the band taking their time over it. The new music is just as layered and perfected as their older stuff and they could have been playing these new songs for the entire decade the core band has existed for all we know. Warpaint are the epitome of a tight, disciplined band.

Ultimately though, the stand out moment of the night is an individual effort from Kokal who performs a mesmerizingly beautiful rendition of 'Baby'. The folky lullaby gently rocks the entire crowd in its arms which, considering it is the first part of a two song encore, speaks volumes for the confidence and ability of the entire band. A truly breathtaking moment in what was an impeccable evening, and as we shuffle out of the art deco lobby, it's all anyone seems to be talking about.

Actions speak louder than words and there are many people within the industry who should take lead from the night's line up and put their talents where their open letters are.
