This is another one I find hard to view objectively, because I was 17 when it came out, and listened to it obsessively that summer. That summer was incidentally one of the best of my life so far, and listening to this album through again took me back to those carefree days.
One thing that always sticks out was going to my first music festival with friends, and being very hyped to see MGMT. I wasn't the only one; they had been booked to a relatively small stage and the tent was overflowing with people like myself. About halfway through the set, during a slower song I looked up and saw a (presumably intoxicated) person climbing up one of the support towers of the tent, which I was standing quite close to. Maybe like 80-100 metres up. I found it funny at first, but the higher they got the more worried I was that they would fall, probably on top of me. Pretty soon half of the crowd had turned away from the stage and more people started climbing. The band had to stop playing and plead with people to get down, eventually leaving the stage. I think the crowd started to boo the climbers then, and they finally came down. MGMT then returned to the stage and played all the hits off the album in quick succession to get the crowd back onside.
Personal anecdotes aside, I do think this is a very important album generally. It is peak 2000s era electro-pop - check out the Justice remix of Electric Feel if you want more evidence of this - and led yo quite a few imitators. The weirder psych rock songs on here make a lot more sense now, having heard MGMT's later work. Overall, well worth a listen, as some of the deeper cuts on here hold up.
