The hip hop music of California has always been deeply stoned, and the wave of instrumental beats that have emerged from LA in recent years have taken this to quite some extreme. The scene around the Brainfeeder collective and Low End Theory club have, in fact, produced some of the most deeply psychedelic music of the 21st century, and Sam Baker aka Samiyam is one of the key figures within that.

If you think games are for kids, or not art, or beneath you – read on. Grand Theft Auto V, while flawed in many ways, proves you wrong. The latest in the controversial and 18-rated series has already broken first-day sales records for just about every artistic medium ever. Huge numbers of adults across the UK will be sitting down to play it tonight. Take that, Hollywood. Or, Vinewood, as the game would have it.

If you're going to make a film whose title mocks a particular tone of voice, it helps to have a voice of your own. And that turns out to be one of the many hugely beguiling aspects of In A World ... , the actress Lake Bell's first film trebling as writer-director after years playing goofball also-rans in films starring the likes of Meryl Streep. A wry look at Hollywood and the (sometimes) wonderfully whacked-out people who inhabit it, the venture takes its name from the doomily spoken opening words beloved (or not) of movie trailers.

This is an incredibly hard album to work out. One major clue comes, though, with its second track, “Maxim's 1”, the backing for which is a dead ringer for a lost track from Cocteau Twins's 1990 Heaven or Las Vegas album. Not that any of the rest of the album sounds like Cocteau Twins, but it does hit a very similar magic formula.

A disembodied, wispy female voice declares “this is not true”, the only emotion left a resignation so acute she may as well be contemplating her imminent demise. On Soft Metals’ “Tell me”, her deliberation is accompanied by electronic music drawing from the pulse Giorgio Moroder created for Donna Summer’s “I Feel Love”, 20 Jazz Funk Greats-era Throbbing Gristle, French cold wave and the drifting vapourousness of the early Orb. On the next track, “When I Look Into Your Eyes”, she sighs “we all die”.

Rod Stewart isn't cool and he doesn't care. He made a complete pillock of himself with the likes of "Hot Legs" and "Do Ya Think I'm Sexy?", but they were some of his biggest-ever hits. He plunged gleefully into the WAGS-and-riches fantasyland of Los Angeles, became a living cartoon of pop star excess, and loved it. "I enjoyed myself hugely, every hour of every day," he told Alan Yentob in this entertaining Imagine... profile.

Sofia Coppola has become known for lovingly sketching out the tribulations of the rich and famous, and reviews of her 2010 Chateau Marmont-set angst fest Somewhere made it clear that critics’ patience with that particular seam had waned. But it has become easy to forget Coppola’s debut film in all this, because it doesn’t fit the pattern.

Robert Altman’s 1973 deconstruction of the private eye movie freely adapts and updates Raymond Chandler’s final completed novel from 1952. With Leigh Brackett (the remarkable female screenwriter who worked on Howard Hawks’s Chandler classic The Big Sleep in 1946 and The Empire Strikes Back in 1981) and his M*A*S*H star Elliott Gould, he offended purists, but caught some of Seventies LA's confusion.
