Big Gigantic, Brasstracks

The traditional business model that originally defined the record industry — the idea that you pay for the music you want to listen to — has slowly eroded over the years. Big Gigantic, the electronica duo from Colorado, embraced the Spotify era from the outset: Their content has always been available for free online. So where do saxophonist/producer Dominic Lalli and drummer Jeremy Salken make all their money? From their live shows, of course, which prove their name is no put-on. Their concerts marry pulsating, jazz-inflected music with elaborate synchronized lighting and bombastic stage presence, and their regular (typically sold-out) shows at Red Rocks Amphitheatre in their home state have earned the nickname “Rowdytown.” Expect that same kind of infectious energy at the Knitting Factory next week.
