Some albums are 'great' because they break new ground, musically or lyrically. Others are 'great' because they represent some kind of pinnacle. Others are 'great' simply because they do what they do with aplomb and are just a huge bundle of enjoyment, wrapped in one small package. Eric Clapton's 1974 461 Ocean Boulevard is, for me, one of those bundles.
A great mix of styles, mainly rooted in the blues, and some fine, fine playing (as expected but nevertheless welcome). It doesn't make any grand statement, other than the sheer delight of music itself.
Which is probably enough.
If you want a real treat, pair it with Slowhand in a playlist and you've got a perfect combo.
