I went to London last summer and just did some basic sight seeing and i want to go this summer agin and wanted to know if their are any events on in the summer like concerts festival I'm thinking about summer in the city or maybe IMATS but just wanted more ideas

Hundreds of events happen in London over the summer.

Take a look on the TimeOut website

Yes, Time Out. But get out of London on an Oyster travel card - not expensive.

Hi yea there is one big convention in London this summer but you need to be ready fast to buy tickets they run our in 4 seconds on the internet. It is Minecon 2015, You can also try going to Vegas there are a lot of things to do there like the David copperfield Go karting shopping outlet( really cheap bought a charge case for $40 there), I also think there is a auto show there. You can also visit the grand canyon from vegas. Don't forget the free water show at belagio

check these sites for events for the summer
