The line between music and film has always been exhilaratingly blurry - musicians often working with the film and TV businesses on soundtracks and the like, and in turn those businesses often licensing existing tracks for use as theme tunes and in scores.
Saturday's lineup at the 6 Music Festival in Glasgow brought together stars from the wildly varied worlds of indie rock, UK rap, jazz fusion, desert punk and electronica. And if one or two names weren't immediately familiar, think again - if you're a TV and film buff, there's every chance you spent the night going, "Wait, hang on a sec..."
Here's how Saturday night went down:
The Shins
Film and TV connection: The Portland-based indie rocker's 2001 song New Slang was used in the 2004 Zach Braff-directed film Garden State, completely transforming the fortunes of the band. The album that followed it, Wincing the Night Away, became a No.2 hit in the US and was nominated for a Grammy.
At the 6 Music Festival: New Slang got an outing, of course, towards the end of the set, but tonight was as much about celebrating James Mercer's band as they are in 2017, with a brand new fifth album, Heartworms, just out. The astute in the crowd will have picked up on Mildenhall from the record, which shouts out Friday night's headliners - "A kid in class passed me a tape / A band called The Jesus and the Mary Chain" - and one of their most heartfelt songs of the evening was The Fear, also a new track. And what was that inserted into closing track, Sleeping Lessons? A snippet of Tom Petty's American Girl!
Bonobo
Film and TV connection: Countless! Bonobo's soulful electronica works beautifully with imagery (have you seen the mind-boggling optical illusions in the video for recent track No Reason?) and his music was used in episodes of The Newsroom and House of Cards. His 2003 track Flutter was the theme for cult TV series jPod and if none of that rings a bell you'll certainly remember Ketto from 2006 being used in Skins, and in a well-known ad for a French car maker.
At the 6 Music Festival: Things just get better and better for the British producer. His recent, sixth album Migration was a No.5 hit (his first Top 20 album ever) and his epic, 17-song set made for a superb closer to Saturday night at Barrowlands. He began with the title track of the new album before bringing on the divine Szjerdene, his regular guest vocalist. Twitter blew up, many of you claiming - in Glasgow and watching at home - that it was your favourite set of the weekend thus far. Cirrus was a standout, and so was Break Apart (above).
Grandaddy
Film and TV connection: Their song A.M. 180 from 1997 was used heavily in 2002 British film 28 Days Later and it's also the opening theme music for the 大象传媒 Four series Charlie Brooker's Screenwipe.
At the 6 Music Festival: American indie stalwarts Granddaddy formed back in 1992, took a brief hiatus between 2002 and 2006 and have very much been back recently, releasing their first album in a decade, Last Place, on 3 March. It feels different to their previous four - longer in the tooth, wiser, more sophisticated and the Granddaddy that performed at the festival seemed entirely comfortable in their own skins (even though frontman Jason Lytle confessed to finding it very hard to not swear during their set, as instructed). Hear the glorious Evermore from Last Place above.
Thundercat
Film and TV connection: If you haven't heard of Kuso, the directorial debut by Thundercat's bestie Flying Lotus, you will as soon as it gets shown here. Its premiere at Sundance in January caused walk-outs and subsequent reviews called it "the grossest movie ever made". Thundercat worked on the soundtrack with FlyLo.
At the 6 Music Festival: Thundercat is one of the most in-demand musicians in LA - a virtuoso bass player who's worked with Kendrick Lamar, Erykah Badu, Childish Gambino and Mac Miller. Signed to FlyLo's excellent Brainfeeder label, he's released three solo albums now, imaginatively melding together jazz, space funk, psych rock and soul. Listen to Them Changes above, a 2015 track included on his recent Death album; below, a snippet of Tron Song.
Loyle Carner
Film and TV connection: Loyle used to be an actor and the keenly observant among you will have spotted him in the Roland Emmerich-directed 2008 adventure epic 10,000 BC. He was just 13!
At the 6 Music Festival: A UK rapper on the rise, Loyle was nominated for 大象传媒 Sound of 2016 and has recently released his startlingly honest debut album, Yesterday's Gone. He's a man who likes to pay tribute. His breakthrough track, Cantona, was an ode to his step-father, a huge Man United fan, and he wrote album opener The Isle of Arran (watch it above) about his grandfather, who used to live there.
Songhoy Blues
Film and TV connection: They Will Have To Kill Us First: Malian Music In Exile from 2015 is one of the most extraordinary music documentaries of recent years. The story of the aftermath of a ban by Islamic extremists on music-making in parts of Mali, it helped introduce Songhoy Blues to a global audience.
At the 6 Music Festival: The joy of the festival is just how many musical forms you can hear over the weekend. Timbuktu's Songhoy Blues are often described as 'desert punk', but their music is all about its bluesy groove. Soubour, which means patience, was our first introduction to the group - the recorded version was produced by Nick Zinner of the Yeah Yeah Yeahs and included on Maison Des Jeunes, the 2013 Africa Express compilation spearheaded by Damon Albarn. They nailed it at the festival, despite only having two hours before showtime with their bass player for the night.
Honeyblood
Film and TV connection: Okay, we'll admit that we're struggling to find a rock-solid TV/film link for the excellent Honeyblood, but we loved the for 2016 song Ready for the Magic, and didn't find it at all unsettling, of course.
At the 6 Music Festival: "People think little girls are precious, like they need to be looked after," Honeyblood singer-guitarist Stina Tweeddale told last year. "We wanted to turn that on its head; girls fending for themselves, with superhuman strength." They're absolutely one of the best bands in Scotland and on home turf (they formed in Glasgow in 2012) they were thunderous. Sea Hearts, above, is from their most recent, second album - last year's Babes Never Die.
