With a stage full of billowing smoke, two blue and green personas—Sonny and Cher—greeted the audience.

It was easy to forget about the wind chills just outside of Roadrunner’s doors as band Half Alive’s “Summerland” turned golden stage lights into summer sunsets before the audience’s eyes on April 11. The rock band from California stopped by Boston on April 11 for the eleventh stop on the “Persona World Tour.” Their third studio album, “Persona,” released last November, explores the nature of humanity and the perceptions we have of ourselves and others.

The two opening acts created an initial buzz of energy that left the audience in eager anticipation of Half Alive’s arrival. Californian singer-songwriter Mehro, whose real name is Sam Sturges, exuded youthful angst as they sang about strife in their love life, backed by a bass line that pushed the subwoofer to its limit.

They were followed by The Walters, an indie pop band from Illinois named after the group’s guitarist Walter Kosner, who had a clear sense of experience and presence on the stage. The lead singer, Luke Olson, danced across the stage with his loosely wired microphone. His spontaneous energy was clear as he improvised a song while the band fixed a technical issue and chugged a Modelo, keeping the audience engaged as the main act drew closer.

Although the band is called Half Alive, they were devoted to making the venue full of life that evening. Josh Kramer, the lead vocalist, captured the audience in his grasp from the first moments of the band’s set as he moved across the carpeted stage.

A few songs in, Kramer was adjacent to the barricade as he looked upon electrified faces and outstretched hands. With widened eyes, he turned away from the crowd and allowed himself to fall onto the pillars of arms.

Backed by the instrumental score of “The Fall,” in which Kramer sings “I’d jump off and into your arms / But I can’t trust the fall,” he placed trust in his fans, allowing his body to fall into the arms of the crowd. The lights strobed a euphoric shade of purple, which filled each crevice of the venue, creating an illusion of Kramer floating through a magnetic cosmos.

When he returned to the stage, he brought the energy transferred through his levitational journey and fell right into place beside two red-suited dancers, all dancing in synchronized choreography.

Half Alive’s choreography and performance is precise and, although it lacks some of the looseness and spontaneity of the opening acts, it serves the overall flow of their set. The transitions from moments within and between songs are carefully articulated and are perfected so as to maximize their impact. The effortless way in which Kramer physically lands into rhythm with the two backing dancers, in time with the climactic ending of “Bleed it Out,” is a rush of adrenaline felt throughout the venue.

A short interlude highlighted the two featured dancers as they wove in and out of each other’s arms through precise and mesmerizing movement. They performed to music that began as isolated beats and grew more elaborate and in sync with the increasing complexity of the choreography.

When the band returned, they changed the tone as they performed acoustic renditions of some of their songs including “Beige,” “Thank You,” and “Creature.”

One of my favorite tracks by the band, “Hot Tea,” was featured in this section. The transformative production is one of my favorite parts of the piece, so I was initially disappointed to discover it would lose that in this live performance. However, accompanying the medley of acoustic songs, I found new appreciation for its construction and the impact of Kramer’s vocals. His falsetto packs a gentle yet guttural punch of emotion that is cleverly contrasted by his rageful belts, displaying the range of his voice as well as the band’s discography.

“Follow along and don’t be afraid to use your voice … I want to hear you sing,” he instructed as he taught the Boston crowd the rhythm and harmony to their track “Songs.” The lights dimmed to a mystic shade of lavender, which reflected brilliantly off the bands’ fire engine red track suits. Smooth acoustic chords scored the conversation as Kramer reflected on the band’s previous visits to Boston and the unique energy of the city’s crowd.

“This is what it is all about—being together, singing songs with you,” Kramer told the Roadrunner audience.

As the band finished their acoustic set, Kramer told the audience not to fear the perception of others and to sing out with their unique, singular voice.

Half Alive’s performance ended as it began, leaving the audience with the buzz of hypnotic synths still ringing in their ears. Following the acoustic section, the energy erupted with some of their biggest hits, “Still Feel” and “Runaway.”

A chanting chorus united the audience and band. As Kramer sang, “I don’t need to run away,” the venue was filled with a rallying cry as he reached from the edge of the stage towards the elevated arms beyond the barricade. Despite the distance, Half Alive left Boston with a final moment of connection.
