Music is an art form, and a live concert is its gallery. If Dredg’s music were to be painted on canvas, it’d be a Salvador Dali masterpiece. Although Dali in fact served as a major influence on the concept of Dredg’s second album, El Cielo, the band’s live show expresses more exquisiteness and emotion than a painting ever can.On Friday, Sept. 21, Los Gatos natives Dredg proved just that as they took the stage in front of a sold-out crowd at the Great American Music Hall.Located in a piss-smelling, unattractive part of San Francisco, the venue itself isn’t as bad as it looks from the outside. Everything from the ceiling and balcony, down to the floor is quite elegant, the perfect venue for a band like Dredg.The intensity was felt both emotionally and physically throughout the show, as the bass lines and drum beats vibrated against the audience’s chests.And as if the slide guitar played occasionally by singer Gavin Hayes wasn’t an odd enough instrument to have on stage, the band brought out another instrument rarely seen at rock shows-a typewriter. Not that the crowd interaction wasn’t good enough, but the typewriter was definitely a unique way to connect with the crowd, as Hayes typed little notes during interludes and almost in between each song. The notes were tossed to certain parts of the room, and the crowd fought for them as if they were fighting for a record-breaking homerun baseball.The one-hour and 40 minute set consisted of material from all three of the band’s albums, plus a few new songs, starting with Yatahaze off their debut album Leitmotif and ending with Triangle from El Cielo. Although the majority of the songs they played were from their latest album, Catch Without Arms, the new songs were undoubtedly well-received, especially I Don’t Know, a new song with a catchy hook that can bring Dredg to mainstream status.The selection of songs ranged from mosh-pit favorites such as the Tanbark is Hot Lava and their heaviest song, Hung Over on a Tuesday, to mellow sing-alongs like Sang Real and Same Ol’ Road. Their most popular song, Bug Eyes, was played in the first half of their set, along with most of their well-known songs.A Dredg show wouldn’t be complete without stand-out interludes between songs. They mean as much to their set as the songs themselves, as they are used as transitions from song to song. These interludes ranged from heavy metal riffs to an almost dancy electronic piece.The energy and passion presented by all four members of the band was amazing. Hayes was spot-on with the vocals, even when his earpiece kept falling and had to be taped to the side of his head. The aggressiveness of drummer Dino Campanella, along with bassist Drew Roulette and guitarist Mark Engles made it a wonderful, breathtaking experience.By the end, after an absolutely phenomenal show, the crowd, most of whom were drenched in sweat, and some in beer, smelled worse than the men who waited outside the venue with cups in hand, begging for their spare change.
