Q&A: Howard Iceberg on his tribute show, this Sunday at Crosstown Station

Since scaling back his duties as an immigration lawyer seven years ago to concentrate on his music, Howard Iceberg has written and recorded hundreds of songs. You could be forgiven for not knowing that — none of the music has been formally released. But all that work finally sees the light of day on Sunday. Iceberg and his band, the Titanics, and about 50 other local musicians play Crosstown Station that night to celebrate the release of Welcome Aboard, a whopping seven-CD, 105-song DIY jumble of folk, rock, country and blues. At his West Side home last week, Iceberg talked about the record and what’s next, now that it’s finally coming out.
