There are three performances of the Creation by Herbie in circulation. As far as I know, this was his sole encounter with the Seasons. It was also one of the last recordings (November 1972) that he made at the famous Jesus Christus Church before shifting operations to the Philharmonie. Its warm acoustics underpin the success of this endeavour.
There is much to luxuriate in here. The singers - choir & soloists - are exemplary. Janowitz in particular, is at her zenith (just listen to the Cavatina in Winter, which is cream set to music). The Berlin Philharmonic of yore excel themselves (to wit: the orchestral introduction to Winter, which they play as if it is the greatest music in the world - and why not). And Herbie is at his perspicacious best. The litmus test of any conductor, Seasons-wise, is the introduction to Summer; Harnouncourt, goaded by his HIP daemon, gallops through it as if the pizza delivery guy is banging on the door. With Herbie's slower pace, the oboe entry is transformed into a songbird which proclaims, mesmerisingly, that summer is at hand. The final chorus blazes with glory.
Debit-wise, EMI has lazily reissued this recording with the 1988 remastering. They could have used their Abbey Road technology to add greater clarity to the texture; the choral pieces in particular would have benefited from such treatment. Even so, the current offering to the market is still an imperative. Enjoy.
