Ball Park Music have done a Big on us and grown up overnight. When the boisterous Brisbane five piece burst onto the scene in 2010, they were met with a throng of equally high-energy fans.  Their first release, Happiness and Surrounding Suburbs was, as far as debut albums go, pretty close to perfect.  An album that jumped up and down, smashed out six singles with unyielding zeal and delivered what it promised – happiness – across all twelve tracks.

You would think that after all of that, the band might need to go down for a nap. But somehow, while embarking on an enormous national tour, BPM managed to create Museum. Birthed less than a year after his older brother, Museum entered the world with a great deal of expectation already weighted on his young shoulders. And he knocked it out of the (ball) park.

The album opener Fence Sitter is a comfortable sound for BPM, a high-energy song with a warm acoustic line and rich, Cloud Control-esque harmonies. The first single Surrender is one of the best tracks the band has ever produced, a ridiculously catchy radio favourite with a killer driving beat. But the record's finest moment is surprisingly its most tender. Coming Down is gentle and stripped-back, and really exposes the band's musical abilities. There are a couple of uncomfortable moments on the album (including the pairing of two very dissimilar songs as Bad Taste Blue Part I and II) but we will just put these down to growing pains.

Museum has seen BPM take pause, explore their sound and find their feet to produce a sophomore release with equal measures of happiness and sorrow… because that's what happens when you grow up.
