Annual trade fair, exhibition, and festival jazzahead! is one of the international jazz community's most important events. Hosted in Bremen, Germany, jazzahead! brings together musicians, bookers, agents, organizers, jazz experts, and music enthusiasts. Due to COVID-19, only half of the scheduled performances of the 2021 edition were actually recorded in Bremen. Among the performing artists is German trumpeter Heidi Bayer. She presents her project 'Virtual Leak', featuring Bayer's original compositions. Although she trained as a classical clarinetist as a teenager, Bayer switched to jazz trumpet at 17. Today she is an in-demand solo trumpeter in small ensembles and big bands alike. Heidi Bayer (trumpet, flugelhorn) is accompanied by Johannes Ludwig (alto saxophone), Karl Degenhardt (drums), and Lisa Wulff (double bass).
