Much has changed in the four years since Tin Armor released "A Better Place Than I Have Been." They added frontman Matt Umland's brother John as a guitarist and second songwriter. They opened for bands like Surfer Blood and Frightened Rabbit. They were named an Alive Band to Watch. They toured the country several times.

So it shouldn't be surprising that the band once self-described as "fast, short and sincere" has evolved from its fist-pumping pop-punk origins. Piano, organ and medium tempos abound throughout "Life of Abundance," a mature sophomore LP if there ever was one.

As a quick respite from their summer tour, they'll celebrate the long-gestating album Thursday at Zeno's with the help of Andy Cook & The Wanderloons, Vacation and The DewDroppers.
