Sludge, have a look at the Steelhouse Festival in Ebbw Vale.
https://www.steelhousefestival.com/
Been going about six years now and getting the more established bands these days.
Much cheaper, nearer and smaller than the bloated Download.
£80 for the weekend. 5000 capacity.
Obviously you’re not going to get the huge headliners that download get but they’ve still had a few ‘names’ there - UFO, Saxon, Nazareth, Thunder etc. A bit middle of the road in terms of rock/metal but the atmosphere is good, people are friendly and because it’s on a smaller scale, you’re not half a mile from the stage.
Edit: just seen your post mentioning Steelhouse.
As you were young man.
