Add Marc Anthony to the list of artists who have had to cancel concerts recently because of an ailing throat.The Latin singer nixed shows in St. Louis and Atlanta over the weekend after having an adverse reaction to the medicine he was taking for a sore throat, according to the Associated Press. Anthony spent Saturday night in a St. Louis hospital recovering from the reaction, although he was released the following day and is expected to be fully recovered in time for a Tuesday night concert in Washington, DC, followed by another show -- which was to have been the tour finale -- on Thursday in Detroit. Anthony's publicist says that the Salsa star plans on rescheduling the missed gigs in the near future, with the new dates expected to be announced possibly as early as this week. Throat-related problems have plagued other soul and rock musicians in the past two weeks. Last week, D'Angelo cancelled a show at Radio City Music Hall in New York City after
being diagnosed with swollen vocal cords, laryngitis, and tracheaitis (see "D'Angelo's Throat Woes Postpone Shows").Prior to that, the skate punk trio Blink-182 had to pull out of seven European shows after members Tom DeLonge and Travis Barker both came down with strep throat (see "Blink-182 Nixes European Shows").
