Regrouped Kansas carries on, performs at the Tivoli this Saturday

Kansas is a very different band now than the group people knew in the 1970s, when the band rose to the top of the rock scene behind multiplatinum albums “Leftoverture” and “Point of Know Return.”

Back then, the band’s original lineup was still intact, with guitarist/keyboardist Kerry Livgren and singer/keyboardist Steve Walsh leading the way as the band’s songwriters.

But to guitarist Rich Williams, Kansas today has, in a very tangible way, come full circle despite obvious differences between the current edition and the original lineup.

For one thing, only Williams and drummer Phil Ehart remain from the original lineup. Now the two are joined by Ronnie Platt (vocals), Billy Greer (bass), David Ragsdale (violin), Zak Rizvi (guitar) and Tom Brislin (keyboards).
