no reason given, just "I don't think"? Yet IF YOU WERE THINKING, and looking, it would actually be a very simple matter.

Here's exactly one picture UP stream, in Chen's photostream... a random woman playing a "random" synth keyboard, 2010, at Paper Sun (now Pegasus). Pay attention to the KEYBOARD: https://www.flickr.com/photos/furcafe/5141675250/in/dateposted/

Now, HERE is a picture from truly "random" Google search, Amanda Kleinman (as Amanda Kleinman) with "Heavy Breathing", from mid-2000s, playing the exact same model keyboard synth. It's identical down to details in the finish, so she likely either PLAYED that night, or lent her keyboard to a friend, who was playing that night, in the picture Chen snapped several years later, dated 2010 (the "whitish patch" on the upper left of the keyboard in this shot is a sticky with the set list, which is the only difference - you can see the finish beneath the paper note in Chen's photostream):

So Amanda takes very good care of her keyboard, and probably doesn't even let it out of her sight when loaning to a friend for a gig like this, like most indie musicians. Good instruments are tough to come by. And yet, by your standard (not looking, don't think, not paying attention) you would question this photograph here as actually being Amanda Kleinman... except for the fact that it resides at the band page, so that pretty much put's it to rest - this is Kleinman, and 98%+ certainty the above pics are as well, save for the lone keyboard example, which is almost certainly her KEYBOARD, seeing as she's just been identified as well, one picture downstream.

And while it's true that any key player can probably play or use any keyboard, certainly not every key player uses the same SYNTH keyboard, and only touring pros generally carry more than one. Board styles, options and such change quite a bit over the years, and some players travel with as many as 10 different synths, but good VINTAGE synths are often difficult to come by, and musicians are very picky about their "options", so not "any" synth will do if it's yours, and you're spending good money for it.

So please tell me, using 2 quick, RANDOM searches, what are the odds of me identifying Amanda Kleinman, her keyboard, and another gal in such close proximity, in images taken 5-6 years apart in time, unless there are TWO Amanda Kleinmans (which I'm not suggesting, at all)? Pretty slim.

But no, you were neither thinking nor looking, you were busy proffing an unexplored opinion, so everything is just a huge mystery, isn't it.
