3.4 - People who know and care about drum-and-bass describe this record in superlatives ("landmark", "masterpiece"). The best I can say is that I certainly like it better than some other well-regarded D&B records I've heard (I gave Goldie's "Timeless", for example, a rating of 1.6). I also like how these tracks keep the mind focused. But, around the 90 minute mark, the breakbeats gets very old and very irritating.
