 Amazon.com: Music: Primitive Streak
Primitive Streak is the last studio recording made by the Subdudes.
Most CDs, there are 2 to 4 great cuts, the rest is just background music, but Primitive Streak has 10 or 11 cuts that you just want to play again and again.
The percussive sound of the Subdudes is very haunting and features a variety of percussive instruments including tambourine and snare drum.

Although Hox genes in mice are only expressed after gastrulation has started, our recent work has shown that initial transcription of these genes is anticipated by earlier events driving gastrulation, and may depend on inducing signals involved in the generation of the primitive streak itself.
Genetic events occurring in the posterior aspect of the embryo from primitive streak to late gestation stages program embryonic tissues to extend the main embryonic axis, and to acquire their axial identity.
Hox genes encode a family of transcriptional regulatory proteins with a highly conserved role in axial patterning in all bilaterians.

 The Too-Weak Rule By William Saletan
"The line established by gastrulation and the appearance of the primitive streak is a clear one," West and his collaborators asserted.
"Developmental individuality, which is central to personhood, is not attained until the primitive body axis has begun to form" during gastrulation.
Prior to gastrulation, they argue, the developing cluster of human cells can't be a person, since it hasn't clarified whether it will become one organism or two.

The conglomeration of primitive streak–derived mesenchymal cells migrates in between the ectoderm and endoderm, forming the embryonic mesoderm.
The 5 pairs of branchial arches that form on either side of the pharyngeal foregut (corresponding to the primitive vertebrae gill bars) on day 22 are the embryologic basis of all the differentiated structures of the head and neck.
Failure of mesenchymal cells to migrate from the somatic mesoderm between the surface ectoderm and the urogenital sinus during the fourth week of development results in failure of striated muscle development.

 bc_martini_eap_3The HeartEmbryology Atlas
The heart and the lining of the primitive pericardial region develop during the primitive streak stage from mesoderm anterior and lateral to the embryonic disc.
The head fold causes the pericardial cavity and the endocardial tube to rotate approximately 180º so that they lie ventral to the foregut and caudal to the oropharyngeal membrane.
The heart tube sinks further into the pericardial cavity and becomes dorsomedially suspended by the dorsal mesocardium, formed from the right and left epimyocardial layers.

 I. Embryology. 6. The Neural Groove and Tube. Gray, Henry. 1918. Anatomy of the Human Body.
After the coalescence of the neural folds over the anterior end of the primitive streak, the blastopore no longer opens on the surface but into the closed canal of the neural tube, and thus a transitory communication, the neurenteric canal, is established between the neural tube and the primitive digestive tube.
Before the neural groove is closed a ridge of ectodermal cells appears along the prominent margin of each neural fold; this is termed the neural crest or ganglion ridge, and from it the spinal and cranial nerve ganglia and the ganglia of the sympathetic nervous system are developed.
By the upward growth of the mesoderm the neural tube is ultimately separated from the overlying ectoderm.

 Chapter 14. Gastrulation and Neurulation
During gastrulation in birds and mammals, epiblast cells converge at the midline and ingress at the primitive streak.
During gastrulation, cell movements result in a massive reorganization of the embryo from a simple spherical ball of cells, the blastula, into a multi-layered organism.
Although the details of gastrulation differ between various groups of animals, the cellular mechanisms involved in gastrulation are common to all animals.

 Gastrulation and Neurulation
Formation of the primitive streak and the notochord are the two important processes occuring during gastrulation.
• Gastrulation (or more precisely, germ layer formation) is the process by which the bilaminar embryonic disc (composed of the epiblast and hypoblast) is turned into the trilaminar embryonic disc.
Gastrulation begins on day 14 and ends on day 19.

 Second City slays Obie crowd
We have two improvisational theater troupes (Sunshine Scouts and Primitive Streak) and two sketch comedy groups (Writers’ Bloc and Piscapo’s Arm), and tolerance for “funny” on this campus is consequently quite high.
The Second City, an improvisational and sketch comedy theater school, was named for the inferiority complex of its home town, Chicago; the poor thing lived in constant darkness, blanketed by big ol’ New York City and her tremendous theater community.
The incredible success of Chicago’s improv and sketch (here on out referred to as sketrov) comedy theater scene is in part due to the power accredited to those two art forms, whereas in NYC improvisational theater was really just seen as a practice tool for real actors.

His meeting with van Gogh, the influence of Seurat, the doctrines of Signac, and a rediscovery of the merits of Degas--especially in his pastels--all combined with his own streak of megalomania to produce a style that had little in common with the thoughtful lyricism of the work of his erstwhile mentor Pissarro.
Gauguin's art has all the appearance of a flight from civilisation, of a search for new ways of life, more primitive, more real and more sincere.
Although his main achievements were to lie elsewhere, Gauguin was, to use a fanciful metaphor, nursed in the bosom of Impressionism.

Endoderm that forms the respiratory and digestive tracts is a sheet of approximately 500-1000 cells around the distalcup of an E7.5 mouse embryo.
The differentiation of gastrulation-stage endoderm is directed by adjacent mesoderm and ectoderm, one of the earliest reported patterning events in formation of the vertebrate gut tube.

 George Graham Reviews The Subdudes 2/14/96
Though the Subdudes last album Annunciation from just about two years ago, was probably their best recording overall, Primitive Streak, is on the same level, and in some ways more interesting and varied.
While it has a lot of time-tested elements, this sound in its current form is a relatively new one, and arose partly as a reaction to the processed and sometimes pretentious sound of commercial pop in the 1990s.
On this album, they are joined by several guests, including honorary fifth Subdude Willie Williams of the Zion harmonizers, who sings and plays guitar, a horn section, the above-mentioned string players, and Bonnie Raitt who adds her vocal and guitar to one especially memorable tune.

 RockNet Album Review: The subdudes
Don't be put off, therefore, if the subdudes' new album, "Primitive Streak" (High Street), evokes a long and winding memory lane.
No musician is an island, after all - well, maybe Beethoven, but he was deaf - and the subdudes, by virtue of their Louisiana associations, connect strongly to the root sounds from which much American popular music has drawn.
With those origins in mind, perhaps it's to be expected that some of the lingering instrumental sound comes from accordion and horns.
