John Reynolds brought a new vibrancy to live music events in Ireland

A native of Co Longford, John Reynolds was a nephew of the former Taoiseach Albert Reynolds, who passed away in 2014.

During his career, John Reynolds founded the Electric Picnic festival, although he had not worked with that festival in recent years.

He also ran the POD and Red Box clubs on Dublin's Harcourt Street and was the driving force behind Dublin's Metropolis, Forbidden Fruit and Vinyl festivals, among many other ventures.

This year he launched a new festival weekend, All Together Now, through his promotions company POD at Curraghmore House, Co Waterford.
