In 1931 there was the first Lower Bavarian youth singing competition in Landshut and Bredl won the first prize together with two of his brothers.
[2] Michael Bredl was a singer and played virtuoso zither, in addition to violin, wind instruments and piano.
In 1957, at the request of Alfred Weitnauer, who was at that time Swabian Heimatpfleger (conservator of regional traditions), Bredl was employed as a teacher in Bad Hindelang.
In 1960 the brothers Albert and Herbert Wechs from Hindelang started to build alphorns again in the Allgäu.
[3] Bredl also contributed to the fact that the rare Allgäuer Scherrzither, an ancient local form of the zither that at one point in the early 20th century had only one player left being a cow shepherd in Oberstdorf, became more widely known and played again by publishing several songsheets for it.
