In spite of a freak storm which flattened the security fencing two days before^[9] and some torrential downpours on the day itself, the 2009 Hevy Music Festival was a resounding success.^[10] Feeder performed brand a new song from their album Renegades for the first time, with this one being "Sentimental", although the title track was soundchecked, it was not performed for the main show. Gary Numan performed a typically energetic set including the classics "Are 'Friends' Electric?" and "Cars". Rainwater damage to his guitar amplifier caused a delay which shortened the subsequent sets but all were completed before the 11 pm curfew.

Glassjaw flew over from New York to make an exclusive UK appearance at the 2010 festival which was a larger event lasting over a weekend with onsite camping. The media response was very positive: "A stellar line up all around.....it'll be hard to see another festival match up in terms of experience and value this year."^[11] and "Innovative, fresh and dedicated festival.....putting on a joyous choice of alt music this summer."^[12]
The festival saw a fresh start, with new promoters, for live music at Port Lympne Wild Animal Park and is expected to continue to grow in future years. In the words of one reviewer: "From the triumph of this weekender, we expect an even better Hevy Festival (in) 2011."^[13]

2011

Dates: 5–8 August 2011
Venue: Port Lympne Wild Animal Park
Attendance: 4000
Saturday headliners The Dillinger Escape Plan and Architects were announced in early March, along with 23 of the planned 80 bands across four stages.^[14] On 1 April the Sunday headliners were revealed to be pop punk heroes – Four Year Strong. They were joined by Welsh rockers Funeral for a Friend. Saturday's lineup additions included the last-ever show for The Ghost of a Thousand, who announced they were calling it a day after 7 years.^[15] In early May eight more bands were announced including Trash Talk who have risen to prominence following their first ever festival appearance at Hevy last year, although they pulled out at the last minute, with TRC and Feed the Rhino stepping in to perform mini-sets in Trash Talk's slot. Rot in Hell were forced to cancel due to the departure of vocalist Nathan Bean. Death Is Not Glamorous were originally booked to play the fest this year along with their tourmates in La Dispute and Touche Amore, although once they found out the festival was at an animal park they pulled out for ethical reasons (they are a Vegan band). Press reviews were universally positive; from Trebuchet magazine: "Hevy is the right sort of festival to really get into music. Talking to production staff, bands, bookers, punters and security there is a strong feeling of community amongst everyone that they are doing this because they love it. Long live Hevy fest see you next year!"^[16]

Venue: Port Lympne Wild Animal Park
Attendance: NA
The 2012 dates were announced on 2 December 2011, with the first announcement made on 27 January 2012 and the second on 16 March 2012.

The organisers of Hevy Music Festival decided in light of "temperamental" weather leading up to the festival they put roofs over the stages. This involved the Rock Sound Stage and the Punktastic Stage merge to have alternating bands meaning there is no time clashes between the two stages. They also merged the Punktastic Stage into the same roofed area with the two stages alternating as the "Main" Stage, while putting the Red Bull Bedroom Jam stage in its own distinct tent.^[17] Will Haven dropped out of the festival on Thursday 2 August and were not replaced. Instead all other bands had their sets adjusted to accommodate the space left by the group.
