Aid charity Oxfam hopes to stage 2,500 concerts across the UK in October in what it has described as the UK's largest music festival.
Alison Goldfrapp had called on people to "make some good noise"
So far, 650 Oxjam events have been organised by members of the public.
"Big or small, it doesn't matter," said Kaiser Chiefs lead singer Ricky Wilson. "Please sign up and make a noise."
Organisers hope the Kaiser Chiefs, Franz Ferdinand and Goldfrapp will be among those appearing at the fundraising live music event.
"We are playing lots of big festivals across Europe this summer but Oxjam is different," said Goldfrapp's Alison Goldfrapp.
"Anyone can join in and help make poverty history through making good noise."
'Dancing till dawn'
Wilson hopes the event will "keep up the momentum of Live8", the pan-global awareness-raising concert that took place in London, Tokyo and elsewhere a year ago.
He has encouraged everyone to take part, "whether it's shaking a tambourine for hours, dancing till the break of dawn or forming a band on the spot".
"We have the support of the music industry and some of the best acts around today," said Oxfam's Gareth Simpson.
"Now we need people to register to take part to help make it a massive success."
