Hi,
Mainstream rock and roll regards the violation of any of the 613 commandments of Our Lord Lemmy, or the seven evil riffs (i.e. Black Sabbath by Black Sabbath) as a sin. Pope Tony teaches that all musicians are inclined to sin from birth. Sin has many classifications and degrees. Some sins are punishable with death by the court, others with death by enforced key change, others with lashes, and others without such punishment, but no sins with willful intent go without consequence. Unintentional violations of the circle of fifths are not considered as sins, since no one can be punished for something he did not know was wrong.
"Sins by error" are considered as less severe sins. When the road manager had to stand in , guitarists would offer plectrums for their misdeeds. The atoning aspect of 'buying a round' is carefully circumscribed. For the most part, getting the beers in can only expiate such "sins by error," that is, sins committed because a person forgot that this thing was a sin. No atonement is needed for violations committed under duress or through lack of knowledge, and for the most part, alcoholic beverages cannot atone for a malicious, deliberate sin. In addition, quaaludes or brown M&Ms
have no expiating effect unless the person making the offering sincerely repents his or her actions before making the offering, and makes restitution to any person who was harmed by the violation.
In prog rock. it is believed that all wilful widdling has consequence. The completely pretentious suffer for their widdling (by humiliation, diminishing sales and the wearing of silly pointy hats) in this world and receive their reward in the reunion tour. The in between (not completely righteous chops or complete novices), repent their sins after learning 'Streets of London' and thereafter join the righteous. The complete wicked also cannot correct their feet on the monitor pose in this world and hence do not suffer them here, but rather, after the backstage party, when 'The Clinic' must be visited.
