One of our test room favourites is turning 40 – and there's a special treat coming for hardcore David Bowie fans

In our dedicated AV test room, there is a wide range of discs that we rely on to put a variety of home cinema hardware to the test. Whether it is a premium 4K projector or a budget soundbar system, every product needs to be put through its paces with the right test discs.

And one of the most enjoyable discs that lives on our shelves is celebrating its 40th birthday this year. Enter Jim Henson's Labyrinth, a fantastical classic that has delighted audiences since 1986.
