I saw Kansas in the summer of 2008. Musically, they are great. Steve's voice is not what it was through the "Power" album, but he sounded better than he had the few years before I saw them. He certainly isn't young, and all of the drugs and alcohol that he used to do were no big help to his voice. Bassist Billy Greer has a very strong voice, and sounds a bit like Walsh- they harmonized well when they were together in Streets, which was Walsh's project after he left Kansas in the early 80's. Greer sings most of Robby Steinhardt's parts. He has more tenor range than Walsh these days. To hear his lead vocal work, check out his Seventh Key project. Violinist David Ragsdale also adds some live vocals for Kansas.
Don't expect to hear anything like "All I Wanted" from Power. Steve probably wouldn't sound very good on it with his diminished range. The best chance you have of hearing a song from Power might be Musicatto. He also struggles a bit on the Elefante material. Fire with Fire and Play the Game Tonight are probably the only songs you'll possibly hear from that era. Still good to hear them though.
For those of you who are big Kansas fans, check out the new Native Window project (
http://www.nativewindow.com), which is basically Kansas without Steve Walsh. Billy Greer sings lead vocals. Some songs have a similar sound, but some were written by outside songwriters and are of a different vein. They will be opening some dates for Kansas on their current tour.
I have tickets to see Kansas on October 17 in Trenton, NJ with orchestral accompaniment. I am looking forward to that. They have a new DVD coming out with a similar format called "There's Know Place Like Home." It features guest appearances by Kerry Livgren and Steve Morse. It should be out in the middle of October.
