Originally released on the now defunct, Earth Mantra Netlabel in 2010, The Grand Hotel Abyss by Christopher Costabile is an incredible and entrancing guitar ambient LP. All of the sounds on The Grand Hotel Abyss were made with guitar, keyboard, percussion, and effects. About each track, Christopher has the following to say: “The Soothsayer” actually arose from a short piece I first recorded several years ago which was initially intended for a film score. It used a similar combination of keyboard and primal, timpani-like percussion. I liked that piece but was unsatisfied with the recording, so I expanded it and made some changes and tuned it in Just Intonation, though the original concept remained the same. For “Harrison Street Variations”, I took a few of the instrumental themes found in a rock song I had written, and I slowed them down to free time and played them in an ambient construction. The ‘Morse Code’ style keyboard sound heard midway through is actually sampled from the original demo of the rock song. This piece is about La Monte Young’s original “Dream House” installation, and its eventual demise due to lack of funding. All of the sounds on “Apollinaire, After the War” were made using a Yamaha PSR-740 keyboard, also tuned in Just Intonation. Some were then digitally manipulated. The dulcimer tone in the far left and right channels is alternately heard forwards and backwards, and this sort of reverse effect is used heavily throughout the album as a kind of thematic variation technique. This composition is an attempt to represent in sound the mindset of the poet Guillaume Apollinaire during and after his experiences in World War I. “Naive Astronomy” was the first piece recorded for this album. It is largely improvised, though many of the improvised parts became standardized for subsequent performances. Everything heard in this piece was played on a Fender Telecaster electric guitar. “…a gaping hole in the brainwave generator…” was the last piece recorded for the album. At first I did not plan to include it, but changed my mind when I realized it could act as a climax, which I felt the album was lacking to a degree. The guitar solo which intrudes upon the final movement was played using an EH Big Muff Pi and an Ebow. I came up with the title when listening back to the piece and hearing the sound of a giant machine in a laboratory (picture what the earliest computers looked like) exploding and emanating showers of colored pixels onto a band of astonished scientists and onlookers. It could also be categorized as a journey into the mind – which is not unlike a journey into outer space. The ‘cricket’ sound heard on “By Lamplight” was inspired by Eno’s attempts with the album “On Land” to emulate nature sounds by using electronic equipment. The cricket in question on this piece was actually a high-pitched keyboard tone run through a tremolo pedal and several other effects. I feel the title of this piece is self-explanatory.
