Ground vibration boom Ground vibration boom Ground vibration boom is a phenomenon of very large increase in ground vibrations generated by high-speed railway trains travelling at speeds higher than the velocity of Rayleigh surface waves in the supporting ground. This phenomenon, which is similar to a sonic boom from supersonic aircraft, was theoretically predicted in 1994. Its first experimental observation took place in 1997-1998 on the newly built high-speed railway line in Sweden (from Gothenburg to Malmo) for high-speed trains X 2000. At some locations along this line characterised by very soft ground (near Ledsgard) the Rayleigh wave velocity was as low as

The band broke up not too soon after this failed audition, citing artistic differences and personality conflicts . David Garza was signed to Lava (Atlantic) Records in 1996. Lava Atlantic is a subsidiary of Warner Music Group. The group’s album, "Me So Twangy", won Best Tape at the Austin Music Awards, 1990 and was described by Peter Blackstock of The Austin American Statesman thusly: "reminded him of outtakes from a very early Beatles recording session."
