On Monday, Passion Pit announced they would be canceling the July dates of their current tour. The band's lead singer, Michael Angelakos, broke the news via their official website. In total, six shows have been canceled.

On behalf of the band and myself, I would like to greatly apologize for the show cancelations [sic], wrote Angelakos. In order for me to ensure that there will be no further disruptions, I am going to take the time to work on improving my mental health. For now, I'd like to thank all of our fans for their understanding.

The electro-pop band, known for their hipster-friendly sound, also scrapped their appearance at Delaware's Firefly Music Festival.

Passion Pit's second album, Gossamer, is set to be released on July 24. NPR, which is currently streaming the album free of charge ahead of its official release, has praised the record for its eclectic sound.

'Gossamer' stands out for its depth and richness; its variety of textures. In 'Cry Like a Ghost,' chiseled, sampled squeals cut sharply through whirring keys and fuzzy low-end before opening up into a spectral, synthesized chorus, NPR's Austin Cooper wrote in a review. In 'Constant Conversations,' the band juxtaposes soft harmonies and concrete kicks to give the slow jam an R&B-style sway.

Passion Pit's debut album, Manners, released back in 2009, was also hailed by critics.  

At its most adventurous, 'Manners' sounds like little else - a pop record that exists in a world of its own, carving a sub-genre niche which only fits their expansive, tonally decadent material, Mike Diver wrote for Clash.

No word yet on whether the band will reschedule the canceled shows. The announcement offers no explanation as to the specific mental health issues afflicting Angelakos. But with the tour set to resume in August, it's safe to assume his struggle is manageable.  Here's hoping for a speedy recovery.
