Mike Stephen talks with:

• Chicago Gay Hockey Association board members Andrew Sobotka and Brian Hull before a game at Johnny’s IceHouse West;

• Coding While Black founder and president Dominic M. Liddell about the need for diversity in the tech community; and

• Plastic Crimewave (aka Steve Krakow) about unclassifiable guitar hero Luther Allison for this week’s “Winter Blues” edition of The Secret History of Chicago Music.

Meanwhile, we wonder if Chicago’s plastic bag ban is working.

This week’s local music is provided by Glamour Hotline.

OTL host Mike Stephen checks out the scene before strapping on his skates with the Chicago Gay Hockey Association.
