A generic term for a rock & roll tribute band that uses a semi-clever name to evoke the famous artist or band it covers, as, for example, the term itself evokes Led Zeppelin (covers, tarpaulin, get it?) See, e.g., By Jovi, Petty Cash, Proxy Music.
Saturday night we went to The Cave and saw that Led Tarpaulin outfit "Springsboomer" -- man, those guys can really play Bruce's stuff from the 70s and 80s!
