Andrew Maxwell, Assembly ****

Thank goodness for a performer like Andrew Maxwell. The Edinburgh Fringe opens just as parts of the UK take a mad pill and start shopping outside normal opening hours. Most comics ignore the mayhem, while some insert a clever line or two, but Maxwell ditches his opening 15 minutes and writes completely fresh material about the state of Britain today in the light of the riots in England.

Josie Long, Pleasance Dome **

Last year, Josie Long, famous for her whimsical comedy and fey delivery, decided to get serious. Disheartened by the election result, she started to do political comedy, but sadly her level of analysis was along the lines of: “Anyone who voted Tory in May's election is a fucking cunt.” One year on in The Future is Another Place, the level hasn't been raised.

Chris Ramsey, Pleasance Courtyard ****

It's easy to see why the Edinburgh Comedy Awards panel shortlisted South Shields comic Chris Ramsey. He's personable, very funny, has a well-constructed show - and is destined for a big television career any day soon.

Sam Simmons, Gilded Balloon ****

Sam Simmons clocks a young girl in the front row and stops the show. “How old are you?” the Aussie comic asks. “Ten,” comes the reply, and he suggests to her mother that this may not be the show for them, so they leave. And just in good time, as what follows is a load of cock and balls as Simmons is dressed in vest and pants which, after he is drenched during a gag, become increasingly, er, figure-hugging.

Luke Haines, Cabaret Voltaire ****

If the cards had fallen differently Luke Haines might have been as big as Blur. As frontman of The Auteurs he was briefly tipped for Britpop greatness, so it is no surprise that he likes the idea of alternative histories. This special show, The North Sea Scrolls, was all about them, as Haines, former Microdisney linchpin Cathal Coughlan, writer Andrew Mueller and cellist Audrey Riley mixed spoken word with punchy lo-fi melodies.

Kieran and the Joes, The Store ****

Kieran and the Joes are a three-man sketch group (Kieran Hodgson, Joe Markham and Joe Parham, working with co-writer Tom Meltzer) who are young, personable and very neatly dressed in shirts and ties - but while they may appear clean-cut their comedy veers nicely towards the dark.

Adam Riches, Pleasance Courtyard ****

From the moment Adam Riches bursts onto the stage, spewing his business cards around as a manic showbiz agent who wants to sign up everyone and everything - including even the venue's walls and floor - this is a show of hyper energy and absurdist comedy.

Tiffany Stevenson ★★★★

The comic is currently appearing on Show Me the Funny on ITV, where her smily disposition is a welcome antidote to some of the sneery critics they have mustered. There’s boyfriend stuff in Cavewoman but Stevenson also delivers a few astute political observations, as well as the occasional unPC gag - such as suggesting Tina Turner's dance moves were inspired by her avoiding Ike’s punches.

The Cave Singers, Cabaret Voltaire ****

A three-piece hailing from Seattle and its environs, The Cave Singers are an authentically hairy proposition. With his tweed hat and red beard, at this Edge festival gig singer Pete Quirk looked like a cross between the late Robin Cook and a stray leprechaun from Finian’s Rainbow, while Derek Fudesco dispensed his lovely, liquid guitar lines from beneath a blur of flying hair.

DeAnne Smith, Gilded Balloon ****

Don’t be fooled by DeAnne Smith’s gamine appearance of boyish clothing and Bieberesque hairstyle. And don’t be fooled either by the way her act begins with a riff on existential angst - prompted by an Australian waiter saying “No worries” when he took her order - which turns into a song (one of a few in the set) accompanied by a ukulele. Don’t be fooled because you’ll realise there’s a lot of much edgier and darker material that she gets away with because she looks and sounds so sweet.
