Tunnels makes no apologies for its love of fusion music, that is, fusion from the raw, ripping, aggressively searching and risk-taking early '70s of Tony Williams Lifetime, Mahavishnu Orchestra and Miles Davis; not the watered-down, lame variety that came along in the late '70s and early '80s. Formed in 1992, Tunnels has evolved into a hard-hitting collective that showcases the extraordinary talents and kindred interplay of its core members - vibraphonist Marc Wagnon, drummer Frank Katz and bassist Percy Jones, a '70s fusion pioneer himself as co-founder of the British group Brand X. Progressivity finds the group pushing the envelope to the next level, with guest soloistsMark Feldman on violin and Percy's rBrand X bandmate John Goodsall on guitar. This special edition of Tunnels is the most ferocious and adventurous yet, fully capable of delivering powerfully intense fusion music in the classic sense, melding rock power with jazz improvisation, complex structures, disciplined ensemble playing, heated interplay and shameless displays of dextrous virtuosity.
