I was not overly impressed with the production values of sheik or a number of albums around that period (tinsel town is another)where frank had obviously taken on digital audio. Sounds a bit wolly, a little better on vinyl.
Pretty much everything (except for the LSO recordings and a live recording made in New York ) were analogue to 1984.
To my ears, the original LPs of Sheik, Joes Garage & Tinseltown sound rather fine. Similarly for the Buffalo album from 1980.
The Ryko cds are a bit grim though. Perplexingly, the original EMI CD of Shut Up N Play Yer Guitar sounds stunning.
