Amsterdam based label Indigo aera is in the middle of branching out with a new sub-label after establishing itself over the last six years. The label will recently launched a new chapter called ÆX. It will put out hand stamped, various artist EPs from a mixture of befriended artists who are considered all inner family members of the label. Like the main label, ÆX is run by Jasper Wolff & Maarten Mittendorff who will also release their own tracks on it. But the main focus is creating a place where friends and more established names share their ideas about experimentation and techno music. Receiving loads of music from friends and their surroundings made them want to create a new platform. The first five EPs are all done and will be released late 2017, with an analogue and Detroit sounds often underlying them all. On the fourth disc the a-side is fully covered with the second appearance of Amsterdam producer KAAP. Known for his long live jams on his own imprint Working Titles he does the same right here. 'Phisiks', over 14 minutes long is a warm and dubby melodic builder that perfectly fits in the ÆX catalogue. On the b-side Ocke W strikes again with a slamming percussive jam. The EP finishes with Taupe who is following up his track on the third chapter, here again an energetic Detroit-esque techno trip.
