Raisa K @ The Glad Cafe, Glasgow, 17 Apr

It’s an impressive line that opener Raivo Sloan treads. Incredibly expansive in sounds they pull from, they also never shaking an underlying tension, finding the centre point where bleary R'n'B rubs against basement-y dread. This is no easy feat, bridging the gap between the kind of wandering ambient that sounds like a whale crying in the upstairs flat and songs that are on nodding terms with genuine pop, but it’s one they manage with real ease, buoyed by a brilliantly dusky voice. By all accounts there’s a mixtape coming this year, and it’ll definitely be worth seeking out.

First becoming known as the keys player in the ever-underrated Micachu & the Shapes, Raisa Khan came centre stage after that band’s reshuffle into Good Sad Happy Bad left her as the lead singer, her delicate, precise voice an about-turn from Mica Levi’s beleaguered holler. Last year’s Affectionately, her solo debut as Raisa K, carried on in a vaguely similar but even more barebones vein to Good Sad Happy Bad’s stock in trade, with a similar melange of the synthetic and the humanly lopsided, the aural equivalent of one of them from I, Robot in a jumper that doesn’t fit.

It’s a great record, but not necessarily one that screams a great live set, but, in this formation – just keys, bass and drums – it gains a new forcefulness, both emotionally and sonically. It helps that Khan produces synth sounds like few others, at once totally sonically implacable but also emotionally dense, carrying an awful lot of conflicting feeling in often hyper-simple arrangements. The garbled synthetic voices that carry Affectionately along are even more pronounced live, their sickly combination of warmth and tension creating a noxiously claustrophobic undercurrent to Khan’s airy singsong.

Coby Sey though, a brilliant artist in their own right, is once again something of a secret weapon; his bass tone the muted, blurred heart of their sound as well as its propulsive core. On Tall Enough, his playing is bouncy and angular, but done with a delicacy that allows it to make total sense amongst Khan’s shifting soundscape. This interplay is never more evident than on gorgeous duet and set highlight Stay, a slice of gorgeously understated heartache and a case in point for what makes them such a magnetic live proposition.
