Theory In Practice

Sweden's Theory In Practice play an ambitious form of technical death metal, a style not often attempted and even less frequently done well, given the high degree of musicianship needed to pull it off. While not quite at the Lethargy level of mania, they slot nicely next to a band such as Canada's Martyr, with harsh death-ish vocals and riffing but with tempo changes aplenty and top-notch musicianship from all involved. Sometimes this form of metal can be unwieldy, with the complex riff changes awkwardly spliced together, but here the songs flow nicely, the band is quite at home playing this style. The first two albums are the most adventurous, with their more recent Colonizing The Sun toning down the complexity a notch, while still retaining enough energy and riffage to please their fan base. As Colonizing was released back in 2002, they are probably done at this point.
