Jethro Tull - Thick as a Brick (40th Anniversary Special Edition) (1972/2012) Hi Res

While never as high-minded or technically facile as the likes of Yes or ELP, Tull began incorporating complex time changes, sophisticated harmonic structures, and highly developed lyrical themes on Thick as a Brick, the realization of the artistic growth begun on Aqualung. It is here that Tull finally bursts into full-blown prog rock mode. While Aqualung was a group of discrete compositions united by a theme, Thick as a Brick consists of one extended piece that occupies the length of the album. Lyrically, Anderson's intentions are a bit obscure here, but the sophisticated arrangements and virtuoso performances are enough to carry the show. John Evan's piano and organ are at the heart of this complex piece, which moves through an endless succession of tempos, moods, and modes in a manner similar to vintage Genesis or the aforementioned Yes, but with a grittier edge. Most importantly, the whole things flows in a cohesive fashion. Thick as a Brick demands close attention, but rewards the same handsomely.
