This is a compilation of his music from the earlier records. It's possible I posted them all before but I'm not sure. Information discogged here.
Certainly we know the ethereally lovely track called Amfora from before:
I personally was never impressed with the Alex Harvey LPs though they are sometimes described as prog, really more glam rock or generic rock with that ridiculous British sense of humor or rather nonsense of humor. Anyways in this 1979 outing Alex plays mostly electric guitar based fusion, with a minimum of attempts at singing. The quality is fair to good, we are definitely not talking about masterpiece level like Big Jim Sullivan or Jeff Beck's Blow by Blow, or Ray Russell, though the basic sound and feel are similar.
The opener, Don's Delight:
Wait for me, Mama, a track where Alex brings out his semiridiculous vocals:
The guitarist and composer for well known one-off French prog band Rahmann, an absolute genius mixed fusion/zeuhl work, is name is Mahamad Hadi. Under the alias Mad Sheer Kahn:
Born in Algiers in 1955, of mixed Persian and Arabic origin, resides in France. Formed his first group in 1975. In 1981, he formed a duo and adopted an image that was quite rare for the time: he spent the 1980s swathed in a turban, deliberately going against what was then the normal practice. His unconventional appearance did not deter the critics, who responded enthusiastically to his playings.
In 1982 the well-known English magazine New Musical Express listed him among the ten best guitarists in the world. During this period he was in fact living in London, where he worked with Velvet Underground's muse, Nico, on the albums Drama of Exile 1 &2, and was acclaimed for his virtuosity.
You can also see on that page, as well as under Hadi, he has quite a discography.
This album is a mixture of ethnic folk with electronic and a lot of sitars. Very little info on the database page here.
