Once again, with "Living Proof"... as with the earlier great CD/Album "SUBTLETY AND PASSION"... Robert Lamm has made what could have been/perhaps should have been the next CHICAGO album. Great writing, great vocals from Lamm and Zosia. with significant contributions from Linderman, Trent Gardner (sounding very Pankow-ish on trombone) as well as Scheff and Hester. Living Proof that Lamm's creative juice still flows...
