It looks like it. And yes you can usually prune back quite hard. But I'm fairly sure there's a specific method - it's one of those remove a 3rd or fruits from the new stems sort of things - so best to search.
Whatever it is, it's not hard as I used to prune my folks black current bushes as a kid.
Looks like it. If you mean, will it survive? ours have always come back following a good prune. Sure you can be a bit more considered if you're aiming for fruit, but otherwise I say go for it.
Is this some kind of currant and I can I prune it back hard?
