If there is one album that epitomizes Chicago's early rock-jazz synthesis along with their consummate, Top 40 instincts, this is it. Filled with memorable songs, impressive instrumental showcases, and great vocal performances, Chicago II displays the rock & brass ensemble at their early peak. Including classics like"Colour My World" and"25 or 6 to Four," this recording presents sparkling performances from three equally brilliant singers. The voices of Robert Lamm, Peter Cetera, and the late Terry Kath combined with particularly precise horn arrangements and exacting production by James William Guercio make this collection particularly noteworthy. Songs like"Make Me Smile" were swinging musical dramas with infectious singing and bold, melodic hooks. Recorded in 1969, II was musically progressive and exceptionally pop savvy. This is Chicago at their absolute best.
