Caravan - For Girls Who Grow Plump in the Night

Not exactly the band's most accessible album — that distinction belongs to 'Cunning Stunts' (1975) — but this wickedly titled 1972 set has plenty of enticing pastoral prog-rock (the famous Canterbury sound) and silky jazz-inflected passages.

If you like this kind of music, check out their 1972's album 'Waterloo Lily' which, in my estimation, contains their finest compositions.
