ALO will offer up a pair of theme nights in San Francisco to close out the year. The band will perform two sets at The Independent on Tuesday followed by three sets at the same venue on Wednesday. The Tuesday theme will be ‘Rewind to Retro,’ as concertgoers are encouraged to dress appropriately, while ALO presumably will contribute some older covers. Then on Wednesday the quartet is dubbing the evening ‘Dress to the Nines,’ encouraging audience members to don spiffy outfits, while the musical accompaniment will include a guest horn section and MC Chrome Tony.
