The plays of David Ireland have a tendency to build to an explosion, after long stretches of caustic dialogue and very funny banter. The Fifth Step, though, is a gentler beast whose humour ends with a simple visual gag. Maybe because this is more personally sensitive territory?

It is a family affair at Supergrass shows these days. There were plenty of parents and offspring filing onto the Barrowland’s famous old dancefloor, and during the encore a pair of excitable, bouncing teenagers turned around and started bellowing for their dad, off on the sidelines, to join in pogoing. He declined, but was singing along with vigour nonetheless.

As you might expect from a Manic Street Preachers gig, literary influences were never far away. A DH Lawrence quote was prominently displayed on the video wall before the group took the stage, and band lyrics would randomly flash up throughout the ensuing performance. This occasionally raised an unintentional eyebrow, as when “Scream to a Sigh” was accompanied by I am a Relic lighting up – somewhat ironic for a group now so long-lasting they’re into a fourth decade.

Mike Scott is The Waterboys. Launched by wide-eyed 1980s folk-rock, and “The Whole of the Moon”, he’s long since roamed into whatever stylistic gumbo he fancies. The latest album – the band’s 16^th – is a concept piece, a 25-track sonic biography of the late Hollywood maverick Dennis Hopper.

Alienation, isolation, and instability are the fruits of working as a “picker” in the chilling labour drama On Falling. The first feature written and directed by the Porto-born, Edinburgh-based filmmaker Laura Carreira presents post-industrial gig economy work as a dystopia.

Genius doesn't always tally with equal opportunities, to paraphrase Doris Lessing. Opera houses have a duty to put on new works by women composers; sometimes an instant classic emerges. But to revive a music drama that hardly made waves back in 1977? Thea Musgrave’s Mary, Queen of Scots has some strong invention, and whizzes you through historical bullet points so quickly that there’s no chance to get bored. But does it deserve a company giving it their all?

When Vampire Weekend arrived onstage they numbered only three and were bunched together at the front with a large curtain draped behind them, obscuring their backdrop. By the time this marathon set ended two and a half hours later, they’d more than doubled in number and had made full use of their surroundings, a shift which summed up a constantly changing, often contradictory show.

'Tis the season for all manner of bugs, colds and illnesses. One had befallen Katy J Pearson, who struck an apologetic note after the night’s first number to say she had been unwell all day and was going to do her best to get through the gig. That added an unexpected element to proceedings, namely by creating the potential for the whole show to come to a sudden halt at any point.

Amid the electro-rock crunch of “Sorry, Etc”, Lauren Mayberry spits out, “I killed myself to be one of the boys/I lost my head to be one of the boys/I bit my tongue to be one of the boys/I sold my soul to be one of the boys”. The singer for successful Scottish indie-tronic trio CHVRCHES says her debut solo album explicitly expresses her feminine/feminist aspect, while also embracing pop.

Props designed like flowers were scattered across the QMU stage for English Teacher's performance. A fitting choice given the Leeds group are evidently in full bloom these days, with an upgraded venue in Glasgow due to demand and, of course, a Mercury Music Prize collected along the way for debut album “This Could Be Texas”.
