Viking metal, Teutonic metal, Mesopotamian metal – labels of this kind are common in fan discourse, media and academia. Whereas some research has investigated such labels and related them to the artist’s stage presentation, music videos, artwork and lyrics, there is still a lack from the perspectives of music production and performance as to how such culturally and geographically associated labels differ musically. This article explores culture-specific production and performance characteristics of Teutonic metal, focusing on how metal from Germany differed from British and US-American productions in the 1980s and 1990s, during which time metal spread to Continental Europe and German speed metal achieved an international reputation for its original interpretation of metal. The study is based on a qualitative interview design with three record producers who were crucial for the rise of German metal labels and their bands: Harris Johns for Noise Records, Siggi Bemm for Century Media and Charlie Bauerfeind for Steamhammer. The findings suggest that performances differed between bands from Germany, America and Great Britain regarding timing, rhythmic precision, ensemble synchronization and expressiveness. Likewise, production approaches varied due to distinct preferences for certain guitar amplifiers, drum tunings, microphone techniques, mixing concepts and studio acoustics. Despite such culture-specific differences, it proved difficult for the interviewed producers to identify distinguishing features. Genre conventions seem to have a stronger impact than cultural origin overall.

The effect of the turning angle on the flow and performance characteristics of long S-shaped circular diffusers (length-inlet diameter ratio, L/Di = 11:4) having an area ratio of 1.9 and centre-line length of 600 mm has been established. The experiments are carried out for three S-shaped circular diffusers having angles of turn of 15°/15°, 22.5°/22.5° and 30°/30°. Velocity, static pressure and total pressure distributions at different planes along the length of the diffusers are measured using a five-hole impact probe. The turbulence intensity distribution at the same planes is also measured using a normal hot-wire probe. The static pressure recovery coefficients for 15°/15°, 22.5°/22.5° and 30°/30° diffusers are evaluated as 0.45, 0.40 and 0.35 respectively, whereas the ideal static pressure recovery coefficient is 0.72. The low performance is attributed to the generation of secondary flows due to geometrical curvature and additional losses as a result of the high surface roughness (~0.5 mm) of the diffusers. The pressure recovery coefficient of these circular test diffusers is comparatively lower than that of an S-shaped rectangular diffuser of nearly the same area ratio, even with a larger turning angle (90°/90°), i.e. 0.53. The total pressure loss coefficient for all the diffusers is nearly the same and seems to be independent of the angle of turn. The flow distribution is more uniform at the exit for the higher angle of turn diffusers.
