Stir (maybe for 5-10 revolutions more than usual as these are strongly proofed ingredients), strain into old fashioned glass with a large cube or sphere (or a coupe with no ice). Garnish with a lemon swath.

I've continuously played with the ratios of this drink over the last few years based on feedback, and recently rolled this out on a new dessert menu at work. Current version is 4 parts, equal parts (.75 oz), using Cynar instead of Cynar 70.
The amaro choice is flexible--I've had it with standard Cynar, Nardini, even Zucca (thanks Drew).
Named after the electronica band. Their music isn't really my cup of tea, but I thought the name was catchy for a nightcap type drink with coffee liqueur.
