If day one delivered on the very specific theme of folk, cialis Boston Calling on Saturday was an erratic, cialis yet fulfilling, medicine endeavor.

Alt-J headlined the evening, and the band’s awkward blend of electronic and guitar music were almost outmatched by an incredible light show.

Alt-J’s set spanned both last year’s This Is All Yours and 2012’s An Awesome Wave. The odd vocal stylings of Joe Newman might divide some, and so could the lyrics that have not really graduated middle school — there are three songs among Alt-J’s two albums that have choruses that literally spell the word “common.” At the same time, the instrumentals and grooviness could get a crowd going.

The set’s highlights included “Taro,” a song that includes a twangy guitar instrumental; and “Breezeblocks,” which uses a Where the Wild Things Are line to an ominous effect. In all, festival attendees leaving City Hall Plaza seemed pump dup by the performance.

Also anchoring the evening was Chvrches, hot on the heels of the release of Every Open Eye, the band’s sophomore album. The Scottish trio has been absent from the city limits since prior to the release of the debut Bones of What You Believe. The band’s last show in Boston in 2013 was up against the fuckin’ Arctic Monkeys, leaving a depressingly attended House of Blues.

It’s 2015 though, and the new album has been out for a single day, and the set was by far the strongest of the day. Lauren Mayberry’s vocals on “Clearest Blue,” a song on the new album, were pristine, yet full of emotion. Plus, the line “Will you meet me more than half way, yeah?!” feeding into an almost EDM-like drop was a rush to hear live.

The album is so new, that Chvrches has not performed it live all that much — as evident in “Make Them Gold” when Mayberry flubbed a line and made light of it after, noting she was singing lines from a demo version. Needless to say, one hopes that Chvrches doesn’t wait two years before the next Boston visit. Perhaps a return trip to House of Blues is in order in a few months?

Elsewhere during the day, Father John Misty bought his trademark tongue-in-cheek emotional (dis)honesty. Songs like “Honeybear” and “True Affection” were wonderful on the Boston Calling stage. Singer Josh Tillman did not speak about his Velvet Underground-style covers of Ryan Adam covers of Taylor Swift’s 1989.

Sturgill Simpson brought his own brand of psychedelic(ish?) country music. His distinct vocals and his band’s backing style made his set perfect for the mid-day rush, following Stephen Malkmus and the Jicks’ straight rock-focused set.

Other highlights included Doomtree, the hiphop collective, which, at times, called to mind another Boston Calling alum, Run The Jewels.

Leading off the day was Grey Season, the fantastic Boston band growing more and more deserving of a breakthrough. The straight

Day two brought to light that real estate is reduced on the festival grounds. The area to the left of the red stage (each set does not overlap at Boston Calling, they alternate stages on the weekend) was noticeably smaller due to the construction at Government Center.

In past festivals, it was easy to walk around the red stage and not walk right into a packed area (a Brand New set from 2014 is a notable exception to this, however). During the Chvrches set, there was an astonishing amount of pushing and bickering among attendees. The fortunate news is that Government Center’s construction is on track to be finished next year (even perhaps before next May’s Boston Calling). While that isn’t time for Sunday’s show, it’s worth noting that this is a temporary, minor issue.

In all, Boston Calling is on track to have another generally positive weekend. While that’s good, a noticeable safeness is noted about the lineup. Saturday’s lineup was very, very safe; Sunday’s lineup comprises Hozier and Ben Howard, which is the very definition of safe. That’s not to take away from the overall positive reactions elicited this weekend — Walk The Moon had its fervent supporters, for example. There are benefits to booking acts that have broad appeal — they spur ticket sales, obviously — but Boston Calling is now an institution. It’s time for Boston Calling to stop booking tastemakers and be the tastemaker itself.
