Big Jim Sullivan Band's Test of Time, 1983

Note on the discogs info page, it says 'successor to Tiger band'. 

This surprised me first of all because it came 7 years later, and because I thought the Tiger outfit was not very good, not progressive, and definitely not fusiony, like this release from the artist called Big Jim Sullivan. 

With respect to the latter, he was a session guitarist for the most part, as you can see here. 

[real name] James George Thompkins

Prolific session guitarist (born 14 February 1941, in Uxbridge, Middlesex, England, died 02 October 2012) whose career started in 1959 after meeting Marty Wilde in a coffee bar.
Launched Retreat Records, with Derek Lawrence.
He played on fifty nine number one UK hit singles, and his lengthy career included stints with Tom Jones and the James Last Orchestra.

So far as I know there's nothing further interesting in his own albums which are mostly cover versions or blues songs, but I could be totally wrong.

Anyways this is just a wonderful piece of electric fusion, very similar I think to the later Jeff Beck masterpieces.  A track called Strange:

A track called Sexy Doreen from the second Tiger album has a nice tritonal chord jump:
