I was at the Alliant Energy Center for Mumford and Sons. This old building is hanging in there as a venue for concerts, hockey, and other community events. It's not the most accessible place but the staff are helpful to get folks in to where they need to go. Seats are usually in good repair. There can be a couple seats that are a bit wonky at times, and then you just move your group over one seat. The bathrooms were relatively clean at the time I got to them near the end of the show.
Inside the venue, there really isn't a bad place to seat, especially when Marcus and the guys went to the back area to play three acoustic songs . Sound quality for this show was really good. I know I had been to some shows that did not sound this good. I will chalk that up to poor sound mixers. There was good security around to assist folks or to card the young looking folks for beer purchases.
Outside the building, parking is always a dice game. I usually come in from Olin and that gate is closed 70% of the time. It was open at street entrance on this night so I went down and found the gate closed near the parking lot. I was bummed. I went in the next available gate and had to park on Willow Island. For seven bucks, I prefer to park on asphalt. But at that point, I was just happy to get parked and get in the admissions line.
It's not my favorite concert venue but I will go there if my band is playing there. And seeing Mumford and Sons was totally worth that night!
