Playing straight up traditional garage rock can be a slippery slope. In many cases questions get raised about if the band is delving into it from a purist stand point of sincerity or are they just playing dress up because they really enjoy costume parties.
With the former it can get a nerdy if they are all just gear geeks that play at mid volume (because they can't turn it up too loud as it may fry out their oh so precious vintage amps) and think music died in 1967 (even if the members of said band weren't even alive yet.)
The latter is akin to Halloween. It's fun to dress up but, unless someone is terminally goth or community theater actor weirdo, the novelty can wear thin pretty quick if mostly they got going for them is wacky schtick.
Judging from their photos, the Ar-kaics dress in a classic style that always looks contemporary. They know that basic black and Levi jackets never goes out of style. Musically, the band floats around the party doing its best to keep both the freshly pressed shirt Nuggets crowd and the rumpled and ragged Back From the Grave fiends happy.
Fuzz box frenzied tunes like album's opening salvo, "She Does Those Things To Me", the early period Black Lips caveman stomp of "Can't Keep Waiting" and "Sick & Tired" and the wiggly chugging of "Givin' Up", "No Good" and "Why Should I" fill a mud bog with grimy old wheel bearing grease that satiates the appetite of those hungry for dirt. For those who feed off the melancholy trips the slashing "Movin' On", the dirgy blues that vibrates off "Slave To Her Lies" and the slow crawl that's the albums closer "Cut Me Down" should be enough to flood black hearts with tears.
It's tricky to take a definitive era of sound from about 50 years ago and stay loyal to it without making it sound too hokey but the Ar-Kaics kick up attitude and put enough sincere energy into it to pull it off pretty darn good.
