The second night of Electric Picnic brought with it one of the tightest rock n' roll performances the Picnic has seen in years, a bona fide Electric Picnic 'moment' - all punctuated with a big ol' dance party with Chic at the main stage.

Texan rock outfit White Denim played a sold out show in Whelan's a few months back but, after seeing them last night at the Cosby Stage, it seems they kept a few aces up their sleeve for their Electric Picnic performance. The sheer musicianship on stage was astounding, as two guitars traded solos back and forth on a musical bed provided by the best rhythm section of the weekend. The several minutes long instrumental break on 'At The Farm' momentarily transplanted the tent back to a Lynyrd Skynyrd gig several decades prior. Excellent stuff.

London Grammar, up next in the Electric Arena, was absolutely heaving. Arguably the biggest breakout band to come from the UK last year, they've always enjoyed a good relationship with Irish audiences but last night's show took it to the next level. Every word was echoed by a chorus from the crowd, in what the band called their 'loudest show ever'. This could well end up being one of those long-remembered Electric Picnic sets, with far more than the couple of thousand jammed into the tent claiming that they were there.

Portishead's first Irish show in 17 years seems to have been 'musical marmite' for a lot of those who witnessed it. We overheard people proclaiming it to be both ends of the enjoyment spectrum, some saying it was outstanding and others finding the minimalist drone put forth from the stage difficult to get into. We were very much the former. 'Mysterons', 'Sour Times' and, of course, 'Glory Box' were a joy to witness live - even if it was something of a downbeat affair.

If Portishead are an introvert's soundtrack, Chic, up next, are the polar opposite. The sheer amount of well known songs that Nile Rodgers has worked on over the years is mind-boggling and they all made an appearance. 'We Are Family', 'Like A Virgin', 'Le Freak', 'Let's Dance' and, of course, 'Get Lucky' had the main stage audience dancing from start to finish.

The biggest cheer of the night arrived when Nile announced that he has just been declared cancer-free by his doctors.

What a night.
