Prototype systems, initial concepts, and early results which have not yet fully matured but are of interest to the Music-IR community may be submitted to the Late-Breaking/Demo (LBD) session. Those interested should submit extended abstracts (2 pages maximum) through the submission website. Said abstracts will be submitted through a light peer-review, and those accepted must then be presented as posters during the LBD session on the last day of ISMIR 2017. Submissions will be accepted from August 16, 2017, until October 22, 2017.
