The Twilight Sad haven't released an album since 2014's Nobody Wants to Be Here and Nobody Wants to Leave. That's 5 long years, a cavernous gap for a band who seemed to be just hitting their stride at that point, but a lot has happened in the interim, and when you look at it all on paper it's not surprising that they haven't been re-entering the studio in any sort of hurry.

How should one judge a Mogwai soundtrack album? Is it right to view it as a new Mogwai album at all, or as something slightly different? After all, it does sound remarkably like the great Scottish instrumental pioneers, the calling cards are there, but at the same time – and presumably because its almost written to a brief – it doesn’t quite follow on the line of progression that evidently runs through their major / full albums as we know them.

The gist A fine new album from Liverpool's instrumental experimentalists Mugstar The music Mugstar have been around since 2003 and they've released numerous albums and singles via various indie outlets. They're something of a cult band (the fact that they recorded the last ever Peel session doesn't do them harm in this respect), and a band that has eluded me until now. Rock Action records are releasing this latest double LP (a seal of approval that will surely perk many a casual listener's ears), and what a fitting label they are for a band like this.

The gist Sacred Paws bring the sunshine to Rock Action The music Many record labels have a "house sound", there are some where I'd happily buy anything that they release, just on the back of their previous output. Rock Action have certainly been a label that i'd trust with my musical prescriptions. They have a knack of signing bands that are almost universally dark, but each of them bring their own ingredient to the table.

The gist Album #3 from Remember Remember, released on Mogwai's Rock Action label. The music Beginning as a creative vent for multi-instrumentalist Graeme Ronald, Remember Remember have quickly morphed into a proper band, and one of the most ambitious ones out there. Their last album, The Quickening (released back in 2012) was a glistening triumph and deservedly got nominated for a SAY award. Their latest, Forgetting The Present, is very much a continuation of that work, honing their "Box of Delights sound", as I like to call it.

Another Mogwai album’s out, it’ll be all quiet then loud guitars, there’ll be little singing, some sampled dialogue, and all the tracks will last about ten minutes, it’s their “trademark sound”.

New Relics sees the return of Glasgow three-piece Errors, mere months after the release of the well received Have Some Faith in Magic.

Formed in 2004 and signed to Mogwai’s Rock Action Records, Glasgow’s Errors third album sees their so-called "post-electro" sound reach its natural apotheosis. Pushing on from the critical success of 2010’s Come Down With Me their third effort concentrates on a sound, which in parts, is reminiscent of the synth slingers of the early-1980s. Opener "Tusk" kicks off the album in great style, a song of swirling intensity that channels the spirit of Gentlemen Take Polaroids era Japan to irresistible effect, creating a progressive statement of synth intent.

A surprisingly cheery euphony opens this record, this is surprising for three main reasons: firstly, the new album is called Hardcore Will Never Die But You Will, secondly, the track in question is entitled "White Noise" and thirdly, this is Mogwai - Scotland's favourite miserablists. If that wasn't unexpected enough, the upbeat nature of the opener continues into "Mexican Grand Prix" (with its traditional rock rhythm and...wait for it...vocals, albeit heavily distorted) and "Rano Pano" which was released to fans late last year as a much needed teaser taster.
