”His melodies are deceptively simple but quite evocative, with a laid-back authority worthy of Miles Davis. You’re listening to the trumpet but all that other stuff keeps clattering around in the background, creating quite the audio feast..” – Divide and Conquer (Dino DiMuro) 

”Album A Guide for Lost Travellers ni osmišljen kot enosmerni napotek k zaključni destinaciji, temveč s svojo dramaturško prepletenostjo poslušalcu ponuja dovolj zvočnega gradiva za temeljit premislek in pester čustveni odziv.” – SIGIC (Miroslav Akrapović)

”X.U.L. vešče prepleta zvočne vzorce, prvine in teksture, ki se gibljejo od sodobnega glasbenega klasicizma pa vse do improvizirane elektronske godbe. Na trenutke so v tem zvočnem pripovedovanju meje popolnoma zabrisane, drugič jih avtor skozi formatiranje dramaturgije po lastni intuiciji in navdihu postavlja v ospredje.” – SIGIC (Miroslav Akrapović)

”The ambient soundscapes that Selko has created delves into elemental questions posed on how to experience music as one entire unit of consciousness. In this experimental project, X.U.L is excited to learn how we could receive music the exact same as everyone else as one body with limitless sensations.” – Divide and Conquer (My Nguyen)

”What at first appears to be moody and quiet turns into a beautifully flowing work that is epic and cinematic in nature. X.U.L’s simple progression gradually becomes ripe with vibrant sounds and textures at every turn.” – Pleaspasstheindie (Bryon Harris)
