Any advertising for a local band that is pasted on every telephone pole around town.
"Bandvertisements littered the town, plasted on ever pole in sight"
An advertisment written for a band, by a band to be self promoting. It is usually very self-absorbed and inflates the actual level of talent the band posseses.
Did you see the bandvertisement those guys wrote? They need alot of work before they are as good as they say they are.
