You can’t talk about ambient music these days without talking about Tycho. As one of the most successful artists in the genre this decade, mastermind Scott Hansen has gained a huge following for music that seems to both take people away to a carefree alternate universe and also seems to keep people glued to their desks in concentration. Green and company once again teamed up with a full band’s worth of musicians to release his fourth album Epoch in December 2016, earning a Grammy nomination for Best Dance/Electronic Album in the process. And it’s been some since he’s played a proper venue in DC - the last time he was here, he performed in the courtyard of the Hirshhorn Museum on a cool fall night in 2015. This time, it was a cool spring night in a much larger space: the six-thousand person capacity Echostage.
