Pink Floyd’s sixth album, ‘Meddle’, is regarded as a prog rock masterpiece. The band had released enjoyable works prior to its release in 1971, but ‘Meddle’ is arguably the first album where all of the “classic Floyd” ingredients came together to create something coherent. David Gilmour has referred to it as the first album since his appointment as guitarist that really made sense, and – as enjoyable as bits of its predecessors are in their own weird and wonderful ways – it’s hard not to argue with that logic. The thunderous bass groove driving ‘One of These Days’ very much looks forward to parts of ‘Animals’; in Gilmour’s ‘Fearless’, there’s a melodic prog songcraft that he would take forward and make the heart of ‘Dark Side of The Moon’ and even the post-Roger Waters ‘Division Bell’, and via the mighty ‘Echoes’ – a side long epic – bits of the Floyd’s soundtrack recording past collide with huge solos, and there’s even a melodic phrase that would be reworked a few years later to become one of ‘Dark Side’s timeless musical touchstones. Unfortunately, there’s the lazy blues of ‘Seamus’, too – something that undoubtedly grew from their Pompeii animal cruelty jam ‘Madamoiselle Nobs’ – but very few albums are perfect.
