Butterworth's songs have a totemic quality because of his tragic and untimely death in the First World War. He is one of the great "might-have-beens" of English culture. You seem to hear the authentic voice of the Edwardian summer here. The settings of Houseman's eerie poems are well-known, and I have never heard a better recorded performance than this. "On The Idle Hill Of Summer" raises the hairs on the back of my neck! The only comparable recording for me (and I do have half-a-dozen others) is John Shirley-Quirk's from the 1960s, no longer available I believe. Technically this is pretty near spot-on, with the balance between voice and piano almost always just right. There seems to be a very slight hint of a phasing problem when listening on some headphones, but this is to be hyper-critical.
The other songs are settings of poems or English folk songs and, although not in the same league as the Shropshire Lad songs, are interesting, occasionally arresting, and very good fillers indeed. I would prefer the track order to place both the Houseman suites together - as published it doesn't quite make sense - but this is easy to achieve if you buy the mp3 version, or if you programme your CD player to do this for you. Very strongly recommended.
