For over 15 years, Salinas’ Cali Nation has been a reggae-rock fixture in Monterey County.

"One minute you’re here, the next you’re gone/ Life begins and ends, and life goes on,” croons Andrew Nack. “Shine like the moon, shine like the stars, love everyone.”

Nack penned “Shine” after losing a dear friend to cancer. The stripped-down, acoustic recording has no effects; it’s just a guy and his guitar, vulnerable and exposed. While the chord progression is basic and the prose simple and somewhat cliche, Nack’s delivery penetrates with an emotional punch that’s powerful, unforgettable and restless.

Nack, the founding frontman of local reggae-rock outfit Cali Nation, has a stash of similar gems that he’s been sitting on for years. These songs are vastly different from the electric Cali Nation, which has reached decibels so loud the Salinas police were once called to pull the plug on a rehearsal. Five years ago, the band released a video for the song “God hates Salinas” performed in front of the city’s John Steinbeck statue.

“Shine” – one of 10 original tunes Nack recently recorded for his solo acoustic debut – has become something that hits even closer to home: His wife Mandi was diagnosed with cancer a couple months ago. Luckily, the cancer was caught early, contained and removed before it spread, but the road has been bumpy and full of uncertainty.

“I’d like to say I’ve had a creative bug in me over the course of the past several weeks, but I’ve been in survival mode,” Nack says.

He knows survival mode well. It’s the only way he’s been able to maintain Cali Nation for so long. With the exception of Nack, the band has been a “revolving door” of players since the beginning.

“The first five years, we had a pretty stable cast of dudes, but it’s a hard industry,” he notes. “People have different agendas. I’ve gotten over the hurt feelings; it’s all about playing music, enjoying it and projecting that out [to listeners].”

Nack says the latest lineup, consisting of drummer Phil Nava and bassist Randall Cope, is very dedicated to the band. Yet years of turnover have worked their way into the lineup, as well. Nack likes to mix things up with occasional special guests, who add elements like a trombone-fronted horn section, bringing a new dimension to a performance.

Along with the solo acoustic album, Cali Nation’s current incarnation is readying to record a new LP, and Friday, the band makes its Cooper’s debut.

“Hopefully, the music can make someone’s night a little better,” Nack says.
