There used to be this band called The 13th Floor Elevators, and they were from Texas and they were the first group to ever use the term 'psychedelic" in describing their sound. They released their first record in 1966, and that effort was titled The Psychedelic Sounds of the 13th Floor Elevators. In terms of influence, they are right up there at the top with Black Sabbath and the Velvet Underground.
Shit came to a crashing halt when Erickson got arrested for having a joint in 1969. Apparently, his legal team had him plead not guilty by means of insanity which resulted in stints at state hospitals where electroconvulsive therapy was the daily special.
However, this isn't the end of the tale. Erickson returned to making music a few years back, and now has a new record on the way. According to the internets, True Love Cast Out All Evil is a collection of songs that Erickson had written but never released before. Not only that, but Okkervil River is serving as the backing band on the album. The frontman of Okkervil, Will Sheff, produced the album.
There are more details over at the ANTI- website, and at this point in time it seems safe to say that this record will be quite good. There will be more information when it becomes available.
