Yeah, very distorted recordings. The good news is the original tapes aren't that bad so you can get better quality rips.
The 1st link is from the Amazon 'Dub Plate Pressure' 8 pack and has the start of LTJ Bukem's set. The rest of the tape is Fabio and unfortunately the rest of Bukem's set wasn't released. The set is from an Amazon event on 29.10.1994.
The 2nd link is from the Amazon 'Upfront' 8 pack. It's a rip of side A (minus a couple of tunes from Fabio) of the Bukem tape. It's from Amazon 'Groove Connection Showcase' on17.12.1994
