`Think Differently' is the debut LP by the duo of Callahan & Witscher. Jeff Witscher has been one of the most daring voices in underground American music for two decades, highlighted by releases on Pan and NNA Tapes.

Jack Callahan's focused, uncompromising approach to sound caught the attention of both Demdike Stare's DDS label and Swiss composer Jürg Frey, who took Callahan on as his first composition student.

Fans of their individual work might expect opacity, disruption, or rhythmic irregularity from their collaboration, but `Think Differently' sounds like a pitbull in a convertible, a sand-kicking beach party, the dopamine hit you get from 311 or Smash Mouth.

It's a punchy, crunchy, highly infectious record. How did Callahan & Witscher cut the path from the ghostly margins of avant garde musics to the gutters of post-grunge American hard rock? In the words of Callahan, "at some point, you start to need a stronger drug." The most potent characteristic of this stronger drug is the guitar.

And not just any guitar, but a sassy, contagious, blithe guitar. Its presence is a drastic shift for two guys who've combined to make dozens of records over the years, not a single one of which has a recognizable guitar sound on it.

Alongside the cool breezes and hyperactive fretwork of Callahan's guitar playing, the songs are backboned by strutting, groove-happy vocals: all bark, all bite.

Every song is a careful collage, light but dense, ornate with gang choruses, soulful femme vocals, autotune and whisper scratches.

This accumulation almost manages to hide the record's potent undertow of dread. `Think Differently' unfolds carefully, a slow-motion demolition that reveals the anxiety of second guessing, the exhaustion of tour, creative bankruptcy, willful misunderstanding, the pain of caring.

Setting this lyrical cynicism against such sonic glee isn't a spoonful of sugar, it isn't a bait-and-switch, it isn't a prank.

After all, the dumb bliss of Sugar Ray's "Fly" shades a song about Mark McGrath's mom dying.

"All Star" is about climate change. Most Sublime lyrics are a bummer. But there's still room for a raised beer, for a dumb grin.

Like these ancestors, Callahan & Witscher aim at maximum uplift, at sounds that warm and dazzle like a sped-up sunrise.

In spite of overdraft fees, in spite of bad art, in spite of self-doubt.
