Vince Power, the music entrepreneur who brought the Mean Fiddler group of venues to the stock market, is returning to the public arena next month with the planned flotation of a venture hosting music festivals in Britain and Spain.

Music Festivals, the company behind the Hop Farm and Benicàssim events, is joining Aim in April, six years after Mean Fiddler was taken private. Power, who is chief executive, and finance director Jon Hale, also ex-Mean Fiddler, are hoping to raise a minimum of £3m in the public offering, advised by corporate finance group Merchant Securities. They plan to use the cash to expand by buying other fledgling festivals in the UK and overseas.

The listing comes three months before this year's festivals. The Hop Farm event, the fourth so far, is in early July, headlined by the Eagles and Morrissey. Previous headliners at the Kent festival have included Bob Dylan, making his only 2010 UK appearance, and Neil Young. In Spain, Benicàssim is in mid July, with headliners including Arcade Fire, Arctic Monkeys and Tinie Tempah.

Power is best known for his time in charge of Mean Fiddler, which he founded in the 1980s with one venue in north London and expanded to included the Reading festival and a 39% stake in Glastonbury. He floated Mean Fiddler on Aim by reversing into a failed dotcom business in 2001, and sold it in 2005 for £38m to a consortium of the US entertainment group Clear Channel and the Irish firm Gaiety Investments.

Power pocketed £13m from the deal but lost £7.9m when his music promotions and pubs business, Vince Power Music Group, went into administration last year. He eventually bought it back from the administrators for £600,000.
