The Sinclair was packed last night for Passion Pit’s headlining concert.  The show was part of a special free five night series of shows presented by Converse’s Rubber Tracks Studio. Lucky attendees were selected from a random lottery, and local heroes Passion Pit took over the Sinclair on the second night. The Replacements opened things up on Monday, while upcoming acts Slayer (April 29), Chance the Rapper (April 30) and Descendents (May 1) fill out the week.

Radclyffe Hall, a local band, opened the show and did not disappoint while playing in a big hometown venue. Their music featured a heavy, grounding beat mixed with a soulful blend of female vocals. Their brief set included “OMG,” “Love Me Tonight” and “Dare to Dream." 

Up next was Baths (and yes, they do list ‘bathing’ as an interest on their band’s Facebook page), a male duo from L.A. Singer Will Wiesenfeld’s energetic performance was juxtaposed by band-mate Morgan Greenwood’s laidback style resulting in an impressive blend of experimental and instrumental sounds with an edge. Their set included “Lovely Bloodflow” and “Animals,” among others.

Passion Pit began their set at around 11 p.m. with a mix of old fan favorites and new songs from their album, “Kindred” (out earlier this month.) They kicked it off with “Lifted Up (1985),” an electro-pop dance track, and the loyal crowd danced along nearly the entire set, which also included “Little Secrets,” “Cry Like a Ghost” and “Carried Away,” concertgoers danced and sang along to nearly every song in the Cambridge club.

Each band member fueled the others as they seamlessly transitioned from song to song. Lead singer, Michael Angelakos, appeared to have as much fun as the audience as he personified the upbeat, energetic tracks that catapulted Passion Pit to fame from Angelakos’ humble beginnings at Emerson.

The set was rounded out with "Take a Walk,” a song from their 2012 album, Gossamer. The audience reached out to the stage, trying to get a piece of the band before they were to make their exit — but leaving is never that simple for a band this popular. The audience cheered, “One more song!” and they reentered with a song written “three fucking blocks from here.” One thing is for-sure about this band: They are a major crowd pleaser.

The concert let out just after midnight — three hours of electro-pop tracks by three distinct yet complimentary bands. The audience left with a couple of free concert posters and (most likely) slightly damaged eardrums—but I didn’t hear anyone complaining.
