83.
I owned Synchronicity and War. Listened to but didn't own the Bowie. Came a bit later to the SRV. Came much later to Tom Waits (I didn't pick up on him until 1993). Couldn't give a rat's ass about the other four.
In 1983 I bought Texas Flood which was a total breath of fresh air from all the synth pop that was on the radio at the time. In later years I acquired the Dio and the Tom Waits. I saw the three of them (not together) live over the years too.
