A couple of songs into Bloc Party’s set at McCarren Pool on Saturday night lead singer Kele Okereke looked around the vastness of the pool-turned-concert venue and proclaimed, “So, I guess this is a pool party.”

Not quite.

The “pool parties,” those would be the community-spirited free events on Sunday afternoons. The Bloc Party concert, well, that would be the corporate-produced concert that a faction within the community bitterly opposes.

In any case, Okereke could be forgiven for not knowing anything about the history of the cool space in which the band was playing, except that he was clearly amused to be playing a former swimming pool.

Bloc Party was wonderful, tearing through a set built around their debut album, that also included some new material from their forthcoming release. (Check out some flickr photos here.) The real issue with the show, however, was the way in which it underscored what an inappropriate venue McCarren Pool is for big-ticket concerts. Five thousand tickets were sold for Saturday night’s show and while McCarren can hold that many people, it’s way too big a crowd for a general admission show with minimal security–with the wrong band and the wrong crowd it’s a recipe for serious nastiness, in fact. (By the way, we’re not advocating for meddlesome event security, just making a point about 5,000 people in a general admission setting.) Second, there’s the assault on quality of life in the surrounding community–5,000 people coming into the neighborhod and a sound system loud enough to be heard a quarter mile away. GL has always loved our outdoor summer shows, but we also recognize that they do have an impact on those around them who might not want to spend the night, say, feeling their apartment thump to Bloc Party or the Yeah Yeah Yeahs.

(Here’s our guess: We can huff and we can puff but what will blow the house down is that there’s a wall of million dollar condos going up along McCarren Park that are close enough to vibrate from the bass riffs at live shows at the pool. Ironically, there’s a story in today’s NY Times about all the people buying McCarren Park condos. We suspect McCarren Pool’s life as a mega-concert venue will be short lived, no matter how many skids corporate promoters manage to grease and how much the Parks Department wants to shrug and say it’s broke when the subject of turning the pool back into a pool comes up. Oh, and are the buyers really that dumb and oblivious?)

Of course, the other unsavory part to all of this is that the Parks Department has turned over a revenue generating machine like McCarren Pool to a private operator without trying to recapture any of the money for the pool itself. Live Nation, which is producing six shows, stands to gross more than $1 million (not counting service fees) from these shows. (Even after expenses, they’re going to make a significant profit from a public space.) Vendors like the Brooklyn Brewery stand to make tens of thousands more getting concert goers drunk. Is there a McCarren Park Trust to recapture some of this money for taxpayers? No. Profits from shows and sales at this public facility are going to line private pockets.
