A.M. is the debut album of Chicago-based alternative rock band Wilco, released on March 28, 1995. The album was released only months after the breakup of Uncle Tupelo, an alternative country band that was the predecessor of Wilco. Prior to the release of the album, there was debate about whether the album would be better than the debut album of Son Volt, the new band of former Uncle Tupelo lead singer Jay Farrar.
Although A.M. was released before Son Volt's Trace, critical reviews were modest and initial sales were low. The album was later regarded as a "failure" by band members, as Trace became a greater commercial success. It was the band's last album to be recorded in a purely alternative country style, as following the record the band began to expand their sound across multiple genres. It is also the only Wilco album to feature Brian Henneman of The Bottle Rockets as a lead guitarist.
The A.M. was a range of automobiles manufactured by the French firm of Ateliers Veuve A. de Mesmay. The vehicles were produced in Saint-Quentin, Aisne, France, from 1906 to 1914 and marketed under the name Automobiles 'Abeille' de Mesmay (hence the AM nomenclature). They were powered by petrol engines of various sizes made by the de Mesmay firm, all marketed under the 'Abeille' (En:'Bee') trade name. The same engines and chassis were used in the AML and AMC range of commercial vehicles.
The company was run by Amélie de Mesmay (née Belin), the widow (fr:'veuve') of Adolphe de Mesmay, who had started manufacturing his 'Abeille' marine petrol engine in 1898.
The de Mesmay company also manufactured light agricultural tractors from 1911 to 1914; they also sold marine and stationary engines in 1-, 2-, and 4-cylinder configurations. Vehicle production ceased at the beginning of World War I. The firm continued to manufacture proprietary engines after the war, and closed in 1936.
A.M. is the fourth studio album by American country music artist Chris Young. It was released on September 17, 2013 via RCA Nashville. Young co-wrote six of the album's eleven tracks. The album includes the singles " Aw Naw", " Who I Am with You" and " Lonely Eyes".
