Ebisu Liquidroom is maybe 5 minutes from the West Exit of Ebisu station. I didn't like how they made people go up the stairs and then back down to get in, especially with a small door right there but I guess it helped when the doors opened in the morning?
There were still tokutenkai from the morning show going on when I got there after 4pm and just caught the end of Maneki Kecha, the imooto group of drop. Unless there were fans coming and going just for their favorite groups, it was maybe 1/2 to 2/3rds full and capacity is about 900. There were tokutenkai for groups going on right outside by the entrance and on the 2nd floor which also had a Time Out Tokyo cafe.
There were some raised areas on the sides and back of the room so you could see even from far away, unlike someplace like Shinjuku Blaze. It wasn't as terraced as someplace like Shibuya WWW though.
Crowd was pretty well behaved and security wasn't bothering people. I didn't see any actually. Maybe craziest thing was one guy standing on the front rail by the stage to get the attention of Anna (light blue) from Guso Drop but then again, Yura (yellow) was running around on the floor whacking people with a squeaky hammer and Shion (purple) was spraying people with water from her mouth also.
Not having a timetable didn't help. And it seems like at the last minute, they moved the starting time up about an hour. I did want to see Junes☆Princess, P.IDL, FESTIVE, and Chu-Z but not enough to wake up early and go to both. Besides, those groups are pretty much performing somewhere everyday?
Guso Drop reminds me of PassCode with the scream vocals and the songs that switch tempo/genre abruptly but, PassCode usually just turns into a wall of noise, at least when I saw them at Idol Koushien and @JAM. CANDY GO! GO! is deserving of being last. So many orange shirts!
A bit late, (hey I only recently got back to England), but I may as well say something about this Liquidroom event. I guess, like some people have said in this thread - what counts as a festival? I would call this more like a normal kindof idol event... just in a bigger venue... maybe a tad longer etc, kindof inbetween ground...
Anyway, I was at Lolisyn at noon at Rockmaykan, then out for lunch, and back at Rockmaykan for my friend's oshimen, Ogura Ayame, who I would highly recommend btw, she is nuts! Oh, and the Rockmaykan event had re-entry.... unlike Liquidroom... even though Liquidroom gave you wristbands... which was really annoying as I was starving in there and wanted to grab some food from the combini during some groups I couldn't care for, but couldn't...
Anyway, I went to Liquidroom as a friend wanted me to turn up for Baseball Girls, and I see why he likes them, the crowd is fun. As for the whole event, seems like people only watched their favourite groups really then fucked off, which is fair enough. I kindof did the same, think I checked out Mecha High - Ayapaso was cute - but didn't really watch the other groups. I was waiting for Heisei Kotohime, who were fun as usual, then Honey Spice. Who were excellent. But... because the event was running so late, I had to leave halfway through Honey Spice's set... (so of course, Aritan told me off for this the next day and wouldn't let me get anything other than a fake punching me in the face cheki). Also embarrassing cuz as I was leaving Kotohime were starting their buppan so they all said hello to me so I had to say "shit, sorry, I gotta go, I'll see you tomorrow..." and then I promptly tripped up the stairs on the way out (luckily out of sight of the girls). Anyway I headed back to Rockmaykan to see Code of Zero, and Lolisyn's second set. I really wanted my friend to see Lolisyn before he left (it was his last day). Buppan was really fun.
So I missed Guso Drop. But saw them a bunch of times this trip anyway, I think they are really fun tbh. Shion always sprays water on everyone, she normally crowdsurfs. Sometimes they all run out into the crowd to hightouch (or in Rei's case, to slap you in the face, hard.) I also still think "slow RAIN @ Tokyo" is the most visually stunning idol song. Your first buppan with Guso Drop will also be the most value for money btw. If you join the Gushin, which costs 1000yen, you get a group handshake, a group photo they post on twitter, a group photo they take with a DSLR and later give you printed out and framed in a wooden frame, and 5 communication tickets, enough for one for each member.
