2015 release including digital download. Compressions & Rarefactions is the fourth solo release on 12k from New Yorker Kenneth Kirschner, who is widely known for epic-length compositions that challenge the forms of modern composition. The album is released as a single CD with a digital download of over five hours of additional music that couldn't be realized within the time constraints of the CD format. Also included is a booklet of essays on Kirschner's music from Marc Weidenbaum, Simon Cummings, Mike Lazarev and renowned visual artist Kysa Johnson, who was also responsible for the album's artwork. Kirschner's title, Compressions & Rarefactions, refers most directly to the physics of sound: the pressure waves in air that are the physical component underlying what we perceive as sound. This concept finds an evocative parallel in the art by Johnson, whose work is about visualizing the imperceptibly tiny physical phenomena that make up everything around us. The title can also be related to the compositions themselves: this is music that alternates between extreme density and extreme sparsity, using those contrasts as a major expressive element as they alternate like waves of pressure and absence in air. Finally, the title also evokes the very long durations of several of the pieces on the album, including two that stretch to over two hours in length.

Great toy for a very active chewer
Color: Green, Pattern Name: Hammerhead Shark, Color: Green, Pattern Name: Hammerhead Shark
My Pomsky who is 9 months has destroyed every toy we’ve gotten him so far and he LOVES this one. He took to it right from the box and hasn’t let it leave his side since. It’s a very durable, hard, chew resistant material and I have a feeling it’s going to last him a long time. Highly recommend! His smile says it all 😊

Durability
Color: Green, Pattern Name: Hammerhead Shark
I have a lab puppy and she LOVES to chew and tear anything that she can up. I bought this being a little bit hesitant by some of the reviews but I will say she has not torn out the squeaker yet,. And it’s pretty loud too (it’s been almost two weeks) and the plastic is pretty durable. The only negative I have to say is the plastic does it sharp ( I’ve almost cut myself on it) but that doesn’t seem to affect her. So overall I’d say this is a great product if your dog needs something durable yet chewable.

A Huge Hit in My Bully Breed House!
Color: Green, Pattern Name: Hammerhead Shark
I have a house full of bully breeds, and this hammerhead shark toy is by far one of their favorites.
I’ve actually bought a few of them so there are extras around the house — otherwise they’d all be fighting over the same one! That alone tells you how much they love it. The shape makes it easy for them to grab, chew, and toss around, and the squeaker keeps them interested without being obnoxiously loud.
What really impressed me is the durability. My dogs are serious chewers, and we’ve had these for a while now. They’re still going strong, which is saying a lot in this house. The combination of rubber and nylon seems to hold up really well to heavy chewing.
The bacon scent definitely helps keep their attention, and I like that I can add a little peanut butter for extra enrichment. It keeps them busy and off my furniture — always a win.
If you have strong chewers, especially bully breeds, this one is absolutely worth picking up. Durable, fun, and clearly dog-approved in this house.

Great for puppies
Color: Green, Pattern Name: Hammerhead Shark
Great for a teething puppy but very loud when it hits the floor. It is truly indestructible!

Great chew toy!
Color: Green, Pattern Name: Hammerhead Shark
Our dogs love them! I have three of the sharks to help them share with each other! LOL
Been crewed on and still look good, long lasting and perfect size for our Golden and Yellow Lab.
