Leave Before The Lights Come On is possibly my favourite Arctic Monkeys tune of all time. It is, in my opinion, one of the greatest tragedies of the modern world that this song was only a single and didn't get a full album behind it.
It came out after WPSIA but before FWN, in a time when Alex Turner was starting to get fed up with the youthful lifestyle of going out and getting utterly blasted shortly before ending up in a bed you never really wanted to be in. There are definitely vibes of FWN in here but at it's core, Leave before the lights come on is the last track of the first era of the arctic monkeys.
The guitar riff, like many other AM songs, is a fairly simple riff and tremendously catchy riff at that. Backed up by the incredible Matt Helders on drums for an energetic frantic drum beat (the highlight of the song for me). Bass is fairly unimpressive but this was replacement bassist Nick O'Malley's first offering to the band so it's understandable (He certainly proves his worth in later albums) And finally, Alex Turners vocals. Great fun to sing, phenominal to hear. Nothing more, nothing less.
If you're a fan of anything Arctic Monkey's definitely give this song a try, you might discover a new favourite!
