All over the world women are joining flashmobs to join the artist and activist Milck for a day of song and sharing. Holler4  are raring to go again after the enormous success of last month’s workshop and flashmob  on Piccadilly. Book your place here to learn the parts to I CAN’T KEEP QUIET at our workshop. Or just come and join us as we flashmob the song at five of London’s iconic locations, singing as we go. This is going to be loads of fun as well as a powerful statement that women’s voices will be heard.
