Six and a half years ago, the duo of Pocketknife (Skooby Laposky) and Cousin Cole (aka Cousin Culo) released handful of remixes, edits and re-works, compiled under the name Tambourine Dream (Discogs) on their joint Flagrant Fowl label. The label only lasted a few years, and it seems the duo are now operating alone. Cole/Culo is still solidly in remix/rework territory, with self-selected highlights including the moombahton "So Emotional" & volume 2 mixtape/EPs he made with Phi Unit, while Laposky has ventured into a few tributes to Arthur Russell (Russell, previously), in the form of a mix of Russell's tracks, and releasing a recently discovered track (which he remixed as Pocketknife) on his label, Wilde Calm Records, where he also released an album of "piano not piano" house music created solely with a prepared piano and raw drum programming, under the name Boonlorm.
In honor of the 100th birthday of iconoclastic composer John Cage (previously), NPR asked 33 musicians about the effect Cage has had on their art. The Los Angeles Times has a tour of Cage's travels and experiences in his native city. MeFi's own speicus has a long and excellent essay up at newmusicbox.org about the performer-composer relationship Cage shared with pianist David Tudor (who premiered, among other Cage works, 4'33"). And if you've always wanted to play prepared piano and lack an instrument you want to fill with nuts and bolts, there's an app for that.
Dead musical instruments... brought back to life by YouTube? Check out this mellotron demo film, a rare trautonium keyboard in some guy's garage, trautonium music by composer Oskar Sala, an original Ondes Martenot, a documentary on the telharmonium (parts 1, 2, and 3), and the Sonovox (used to funny but not-suitable-for-work effect in this parody of Sparky's Magic Piano). Meanwhile, avant-gardists have revived the art of prepared piano, but more mainstream acts such as Tori Amos and Ferrante & Teicher have also experimented with it. Last but not least, another performer of prepared piano is Margaret Leng Tan, but I think she should get more accolades as the best virtuoso of the toy piano since Schroeder from Peanuts.
