Kaos was at The Warehouse, then it morphed into Soak.
Must admit I thought that, but I've been reliably informed that Kaos was Fridays and Soak was Saturdays, at least for a time. Can't honestly remember cause my visits to Leeds, frequent as they were, depended on what was happening in Sheffield. I didn't start visiting regularly until UYR and B2B were both running at the Music Factory, when it was just easier to stay in Leeds all weekend
Pretty sure Soak was only monthly once UYR started
For years, I only had one Sasha tape, which had 45 mins of the 8 Feb 91 Shelleys mix on one side and 45 mins of this on the other (from Octave One to Overweight Pooch and then E-Lustrious through to the start of TC1991). It was always the one that got played on the way to big does like Vision, Fantazia etc etc and often first out the box when we got back home and wanted to unwind.
Amazing to think I only got the full mix over ten years later, and I still listen to it about once a month.
Ain't this site brilliant?
